Hello, Im trying to get advice on the best way to upgrade my CPU? I've been into PC gaming about a year now.. And I play games like WoW, NBA 2K10, and Modern War Fare. So what I want to know is should I upgrade to the new i5 or i7 Technology or will I be ok by grabing a Quad Core Proc and calling it a day? Because my system is ancient! Im running a Intel P4 3.0 800 Ghz CPU with 2 gigs of DDR2 Memory with an 9800GT Nvidia Video Card, running on a asus 775 socket mobo... Can you tell me what will be the best upgrade for my Cpu with or without my old Mobo? I'm trying to spend under $400.00 if I can get away with it! I'm not an extreme gamer but I want my CPU to be good enough to play just about anygame at max settings and be able to last at least 3 yrs before I have to upgrade to a better Proccesor?
