New computer

[Concillian]

My computers blue-screens have become very frequent, about once or twice hourly. It usually happens when I open a file in windows explorer. I'm not certain if this is indicative of a memory leak or ram failure, but in any case, I have decided to upgrade to win 7, and in the process, realized my current computer could use an upgrade itself. So here I am looking to purchase a new computer for myself this time (not my wife) capable of playing Diablo 3, Torchlight 2, and Darkspore. I don't have a lot to spend. I want the computer to be upgradable. I want the computer to be able to multitask also, not just games. I went to toms hardware, but was unimpressed with their choices, though reasonably priced, were highly unmodifiable for future upgrades, and getting just the components I "want" will cost be a lot more than purchasing a pre-build machine. After a bit of research on the major sellers websites, I believe this machine fits the bill perfectly, and is very affordable, but I'd like some opinions of those who are more computer savvy than I. Thoughts? I'm open to suggestions.

ibuypower.com or cyberpower.com and you can put together just about anything you want for a pretty modest builder fee.

Or a pre-selected system at newegg like this:

an i5-2400 will be marginally slower in applications that use 6 cores, but there are very few of those applications. It's no slouch. If you go to one of those websites, you can put together a similar machine with features you're most interested in (more memory if you want, or a better video card.)

The video card in those systems is the same. A 6770 is just a 5770 with a new label on it. 6770 are sold only to OEMs, basically so OEMs can say it's a 6 series card, even though it's unchanged from the 5 series (since it was a pretty small jump anyway.)

AMD is just plain not the way to go right now. Their next gen is due out mid-year. I'm praying they're something more competitive. Current Blizzard games HEAVILY favor Intel. And a single Intel core right now significantly outperforms a single AMD core at a given clock, so Intel Quads are often as fast or faster than AMD Hex cores in multithreaded applications.

shows i5-2500 vs. 1090T. 1090T is favored in only 3 benchmarks out of 2 or 3 dozen spanning most things you'd use a computer for.
A 2400 is marginally slower (200 MHz slower), and generally the best all-around bang for the buck for people wanting a decent all-around system. If you're dead set on AMD, wait until Fall. Their new offerings should be pretty significant improvements.
