I have a M4A785TD-V EVO, AMD Phenom II X2 550, 8.00 GB Dual-Channel DDR3 @ 669MHz, and 1024MB GeForce GTX 560 Ti.
I tried the Guild Wars 2 beta and found the game to be fairly laggy and was told my CPU should be upgraded. I have no idea what the best CPU is to upgrade to. I called the local computer shop, they suggested one 3.4gb x4, (forget the exact name) but said I probably wouldn't notice much of a difference.
I was told when I got the motherboard it would hold a quad core processor and upgrading would be easy. Any suggestions on a good CPU I should get for it?
