I cant deal with amd sorry reccomend an intel platform computer please,
I used to have a computer like yours, amd 64 x2 5000+, 4gb ocz 800, dual 8600 gts 256, 750gb hdd, but that was 2 years ago.
The mobo fried and every other amd mobo i have owned has fried within a few months. Intel is worlds better from my experience
Also I dont trust ATi, always been a nvidia fan.
