Hi I have a Asus P5E3 Wifi @n Premium motherboard, A Intel E8400 processor O/C'ed to 3.6GHZ with CORSAIR XMS3 DHX 4GB (2 x 2GB) DDR3 SDRAM rated at DDR3 1600. I'm looking to upgrade my CPU, specifically a Quad Core, good for gaming, I will also upgrade my GPU, but I'll decide what to get for graphics. I'm trying to get a better CPU and since Intel stopped production of these 775 socket CPU's supply is really low. So what should I get? Maybe a Xeon processor? What do you think?
