Now really isn't the time to get an Athlon.
The 939 pin athlons are just around the corner, which is the migration path of most of the athlon sets.
754 series sets will still only have a single channel 128 bit pathway. It's not worth it.
Wait until the 939 pin, and get dual channel memory transfer in a non-FX Athlon64. Even if you're only getting half the cache (1 meg vs 512kb) on the 939 pin versions, chances are you will be able to overclock it more because it's a smaller die space.
46 pages... I wanted a motherboard review, not a dissertation :)

are so cheap that it rarely makes sense to put money into an older machine
when a newer, more powerful machine is available for about the same price

Of course, special needs require special hardware considerations, but that

Remember that CPU pricing is non-linear, where the current top-of-the-line generally has a very stiff price premium. One thing I did a while ago was to chart the price/MHz of a particular line of CPUs, then I bought the CPU right at the top of the linear range before the curve upward began.

Then I noticed that I never swap CPUs out anyway. Motherboards are cheap enough, I swap an entire motherboard with its CPU. In fact, usually I swap out entire computers.
Since we use all our computers, I usually build a complete new computer, get it working, swap it for the older one, and keep the older one handy for a while as a hot spare in case something goes wrong with the new one. Then later I find a good home for the older computer.
(Now that I'm buying Lian Li aluminum cases, I'll probably start swapping motherboards into cheaper steel cases, and putting new motherboards into the Lian Li case.)
But anyway, I might get a socket 754 motherboard and chip. It will outperform any computer I currently own, and it should have adequate horsepower to play Half-Life 2 and Doom 3.

I find this to be the single most efficient way to keep on top of technological evolution.
Someone wants a PC from me, they get a KT400 and AthlonXP, I get an Athlon64 and mobo to replace it. RAM, video and HDDs stay here until I need faster parts, or in the case of HDDs, they get dumped for being too small.

In any case, it is important to remember: Athlons are not Pentium IVs. Athlons do not have the performance hit that P4s have with lower bandwidth. Currently, very few applications care whether you have single or dual channel memory--the performance difference is in the low single digits. After Athlon64s significantly ramp up in clock speed, we wil begin to see a greater advantage of having more bandwidth, but not before.
Also, I wanted to note that currect 512K Athlon64s DO NOT have a smaller die space. They are more or less 1MB chips with half the cache disabled. Future revisions will actually cut out the cache, but for the time being AMD needed to market a cheaper Athlon64, and didn't have the time or money to modify manufacturing equipment to manufacture a third completely different die. That said, die space doesn't directly have anything to do with how overclockable a chip is.

Or, to put it less obliquely, that's a strange comparison. A PowerMac G5 is for someone who wants a Mac. An Athlon64 motherboard is for... well, not someone who wants a mac.
Hope this helps.
P.S. The Athlon64 actually offers great price/performance in plain old 32-bit mode. It gets even better in 64-bit mode, but there's no reason to wait for ready availability of 64-bit software. Just as there's no reason to hold off on buying a G5 for a fully 64-bit MacOS.

It was less than _half_ the price of an 1600 MHz G5 Mac with a Radeon 9800 Pro (i.e. previous generation), 512 DDR 333 RAM (yep, slower), a smaller hard drive, etc.
Even after changing the Mac's DVD writer to a DVD/CDR drive, it still stayed more than twice as expensive, and offering far less horse power. Go figure.
And if I'm to factor in the cost of buying all my software again, if I were to "switch"... well, you get the idea.
So there you go. Maybe you can't see it, but half the cost for _more_ power, sure looks like enough of a price advantage to me.

All you have to do is worry about how much computational power you want and how much money you want to spend on a CPU and motherboard.
Let's face it, if you hope to see an appreciable speed bump when you upgrade, buying a first-generation chip and plugging it into a first-generation motherboard with the expectation that you'll get that big speed bump when you plug in a second- or third-generation chip a couple of year's down the line is the wrong way to go about it. Yes, the new CPU will have a faster clock speed but the rest of the motherboard will be two years out of date.
Take my AMD Athlon motherboard as an example. When I bought it a couple of years back, together with an 1200MHz CPU (then the second fastest chip in the range), it had all the latest bells and whistles. But today, its support for USB 1.1, DDR2700 RAM and even PATA RAID make in far inferior to the vast number of motherboards out there that support USB 2.0, DDR3200 and 3500 RAM and SATA RAID, not to mention IEEE 1394 (FireWire), Gigabit Ethernet, better POST reporting, etc.(I won't even start to debate the performance benefits of newer nForce2 Ultra chipsets over their older counterparts.)
To match the features of the latest AMD Athlon/Athlon XP motherboards with my older motherboard I would have to add in at least two, maybe three or four, PCI cards. This would work, but it would be an inelegant (taking up valuable PCI slots), costly (PCI cards aren't free) and inefficient (PCI cards require drivers, configuration, etc) solution. Far better and cheaper to upgrade the motherboard along with the CPU in one go, allowing me to put the older motherboard and CPU combination into another machine/my spares box/the charity bin.
Seriously, when buying a motherboard and CPU, look past the upgrade path. It's a serious red herring, even for PC enthusiasts such as ourselves.

I will admit, though, that if you use KDE/Linux there are some things that could definitely use a speed-up like switching between apps and loading the GUI shell. However, beyond that, modern operating systems work just fine with today's processors.
The argument to this is always "what if you're doing serious number crunching or graphical rendering?", but the answer to that is that there are dedicated DSPs out there that can perform those computations much more efficiently than the CPU. Relying on the CPU to give good Quake framerates is like relying on your auto-body shop to soup up your ricer. Yes, there are some increases in performance, but the real horsepower behind these things lies in the video card and engine, not in the CPU and rice spoiler.
I'm all for improvements in chip technology, but software lags so far behind the capabilities of modern CPUs that it's preposterous to climb on the upgrade cycle, regardless of the circumstances.

First of all, games are not necessarily limited only by the video card. Certainly if you run the latest games in the highest resolution with 8x AA, your video card will be the bottleneck, but often times only these extreme situations make that true.
Morrowind, for example, doesn't really care much about your video card. If you have a Geforce 3, it is happy. It does, however, care about your CPU. If your CPU is not god incarnate, your frame rate will be limited, particularly in some of the more dynamic scenes. The fastest CPU at the time of release, the P4 2.53GHz, could not muster much of a frame rate regardless of video card.
Any 2D game will be CPU limited as well. Baldur's Gate 2 still chugs on some of the extremely large fights even on my AthlonXP 2500+.
In Starcraft, I assure you that my carrier attack will slow your frame rate regardless of your CPU.
Other than in video games, I am currently transcoding a Babylon 5 video from MPEG-2 to DivX (using Xvid) on my laptop. It is an Athlon64 3200+--the fastest laptop processor money can buy (well, strictly for video transcoding, the highest end Pentium IVs are actually slightly faster) and it takes about 6 hours for a 2hr movie, 3 hours for an episode. If I had a 20GHz Athlon64 it would still take forever.
To come to a point, yes, modern operating systems do tend to run fine on modern fast processors (with the possible exception of WindowsXP and anything running KDE or Gnome2
A few other examples:
- There isn't a computer on the planet fast enough to install Gentoo Linux quickly.
- FreeBSD's make world will be noticeable non-instantaneous for many GHz to come.
- Waiting for Visual C++ in Windows to compile... Well, anything at all, is not instantaneous even on an 8-way Xeon.
- Waiting for Regedit in Windows to search for a certain key or value will NEVER be fast on ANY computer. I don't know what search algorithm Microsoft chose for that thing, but it's damn slow for searching through just 10 or so megabytes of data.
- Anything ever written with SWING in Java. It was slow in 1996 and it's slow now. To avoid flames, I love Java as a language, but SWING is slower than a dead slug stuck in frozen molasses.

In English: Cheaper motherboards for the dual channel Athlon64s.
Athlons are efficient with their use of memory bandwidth, so current Athlon64s don't really care about the second memory channel much at the moment. It has a minimal effect on performance. However, since processor technology moves more quickly than memory technology, future 3+GHz processors will start to see a significant benefit from the added bandwidth. Of course, by then, DDR2 will be readily available so we'll just have to see how it all turns out.

Re:AMD64 vs. Opteron (Score:4, Informative)
The AMD Opteron is a processor that uses the AMD64 instruction set. It is designed for workstations and servers and can be used in a glueless SMP setup for up to 8 processors (>8 processors is possible but requires extra core logic chips to connect them together). It runs at clock speeds of 1.6GHz up to 2.2GHz (current top speed), has 1MB of L2 cache and 128-bit wide memory controller integrated onto the die, as well as 3 hypertransport links for interprocessor communication and I/O. It is marketed under model numbers such as 140, 246, 848, etc, with the first number indicating the maximum number of processors usuable in an SMP system (1xx chips for uniprocessor systems, 2xx for duals and 8xx for up to 8-way systems) and the second two numbers showing relative performance. Personally I am quite fond of this particular numbering scheme for the processors.
The AMD Athlon64 is another processor that supports the AMD64 instruction set. It is designed for desktops and mobile systems, so it will not work in multiprocessor configurations. Currently it runs at 2.0 or 2.2GHz with 2.4GHz chips on the horizon. They have either 1MB or 512KB of L2 cache, depending on the model, either a 64-bit or 128-bit memory controller (again, depending on the model), and are sold using two main model numbe schemes. The first is for the stock-Athlon64, which are sold as 3000+, 3200+, 3400+, etc. These numbers show a rough approximation of their performance as compared to an Intel P4 running at the 3.0GHz, 3.2GHz and 3.4GHz (AMD may not say this officially, but it's fairly obvious that this is the intention of the model numbers). I don't like this model number scheme too much, but on the other hand I don't find it any better or worse than the totally useless clock speed (MHz or GHz) rating that is traditionally used to sell chips. The second model scheme is for the Athlon64 FX line of chips, a chip targeted at the high-end "enthusiast" market (read: bratty kid gamers with too much of their parents money on their hands). These chips are sold as the Athlon64 FX 51 and the upcoming Athlon64 FX 53, with the numbers merely referencing the relative performance of the chips.

Register size/Bus speed/hypertransport all can be added to current 32bit platforms. The introduction of 64bit instructions as far as I can tell will not offer any benefit to a gamer.
It's not like you can "pair up" instructions now... those instructions that used to be 32bit, when recompiled simply take up 64bits now, right? If your video games don't require hugely accurate numbers... The 64bitness of an instruction set adds nothing!

And don't give me that crap about 64bits means more width for memory transfer. That's bullshit. Your nice little 32bit instructions are taking up that bandwidth already just by the recompile for 64bits.

Sometimes the logic of Mac fans is a bit too strange for me to follow.
Here's another idea: if a Mac is all you need, good for you. By all means, stick to your Mac. I'm genuinely glad that you found your dream computer.
But for some of us a Mac just doesn't fit the needs. E.g.,:
- Games. Yes, I know that you can buy a whole 20 games for the Mac, some of them almost 10 years old (e.g., Fallout), and some of them Solitaire clones that you can download for free in the Windows world. But some of us, you know, need more games than that.
- Price. Yes, the dual G5 is a nice computer, but the price I've paid to build my Athlon 64 3200+ computer, including a shiny new ATI Radeon 9800 _XT_, was a _third_ of that. Or half the price of a single processor 1600 MHz G5 with 9800 _Pro_. On account of keeping my old case, hard drives, RAM, PSU, etc.
And if I'm to add the price of buying all my old software again for a "switch", the price comparison is getting even more disastrous for the Mac.
So basically all I'm saying is: the right tool for the right job. For some of us the Mac is just _not_ the right tool. Our choice is simply "Pentium 4 or Athlon 64".
