i have a msi P4M800Pro m/b, currently running a intel celeron d 2.66ghz and am in desperate need an upgrade. i have done some research into this and i have found a few good processors and i was woundering if anyone could give me some advice on what they think the best upgrade would be for me. i have a radeon 256 MB AGP 8X/4X gfx card. the socket for cpu is 775. i will be using my system for gaming (obviasly not top end) and would appreciate any help on this matter thanks
