I was just wondering If I were to upgrade to say amd 64 3800+ 90nm Rev. E and either the 7800gtx or next ATI, would I notice a significant speed difference in games and general computing at on my 17" lcd 1280x1024. I play alot of games and just use the computer alot in general. Im waiting for the next ATI card before I make an mobo/cpu and vid card upgrade. I plan on hopefully selling my card for around $250 this summer if I upgrade and spending approx. 800 dollars net (~1000 before selling card). Would this be a good upgrade option? or should i go for like a 4000+.
