Yes I agree with CaptainHaplo, I have an Asus M3A32-MVP Deluxe that is AM2+ and after a bios flash now run a Phenom II 2 core (Deneb), 3.7ghz, I am looking to upgrade to a 4 core soon while they are still available, but your memory and video card is more important.

BTW, with my current system I am finding the biggest problem is running XP pro 32 bit, I have to switch to Win 7 64 bit soon!
