Hi all. I am just about ready to pull the trigger on a new PC. I have decided on a 7900Gt, Raptor drive (non raid for now), 2Gb Corsair XMS mem, an ASUS board - probably one of the A8N flavors - not sure yet, I'm just partial to Asus. I just can't decide on the 3700 San Diego CPU or something like the 4400 X2. Currently, the main objective is playing BF2. What are the 4400 X2's advantages? Is it worth the extra $200? I don't really want to go over $400 - $450 for the CPU. Thanks in advance.
