I too have socket a A mobo and am looking to upgrade on the cheap. I want to play Test Drive Unlimited, but the minimum AMD CPU is 2800+ (mine is a 2500+). I looked into buying a 3200+, but trustworthy used ones are so expensive that you might as well do a full budget upgrade. Another thing to consider is that the newer components such as Athlon 64 X2 CPUs and GeForce 8 and 9 series video cards use less power, thus lower wattage PSUs, less heat (more reasonable coolers), and lower electricity bills.
