Simple tasks like switching between Firefox and Thunderbird are driving the load on my machine up over 4, and if I'm trying to run Amarok at the same time, it drives it up to 8. In fact, my machine frequently climbs up into the 7-9 range, bringing my apps to a crawl and frustrating the hell out of me.
So I've decided it's time to buy a new computer. I'm going to replace my aging Sony Vaio desktop machine (which runs Linux) with something newer that has more RAM, a faster processor, and a bigger hard drive.
The thing is, I'm not entirely sure where to start looking. A quick walk through Circuit City a month or so ago lead me to believe I can get a rather "big" computer for as low as five hundred bucks, which further leads me to believe that if I were to buy something online, I can get a huge pile of RAM, a fast processor, and a big honkin' hard drive for even less.
I run Kubuntu, and use KDE as my desktop (though I occasionally switch to Gnome when I get bored) and I mostly use Firefox, Thunderbird, OpenOffice.org, Amarok, and run PokerStars in wine. I'm looking for something that can do all of that without slowing my machine to a crawl.
Anyone have any suggestions on where to start looking?
Edit: I don't think I have the patience to build my own machine out of individual parts. I also don't have any real loyalty to any particular company or architecture. New Egg has lots of machines with AMD processors, and though I've always had Intel processors because more things seemed to run on x86, that's not as much of an issue as it once was, right?
