"Yes, it is true that the fastest chips are made by Intel, but when you look at the cost of typical (not high end) machine, AMD is hard to beat, especially when the graphics in and APU will work fine for you."
Interesting... care to give an example? In most cases, I feel I can spec out an Intel based machine for the same price (also using the IGP) that is fast enough for HTPC use and runs cooler and quieter while using half the power... unless you actually need the extra GPU power or the additional cores AMD likes to throw in at the same price point, what's the point in going with AMD? A Sandy Bridge Celeron/Pentium is more efficient and provides enough processing power for any HTPC I've seen.
I'd actually like to start buying AMD again in order to give them some support, but Intel's where the efficiency bang-for-the-buck is at right now... this may be different for those of you who don't pay your own power bill *cough*mom's_basement*cough* :p
