Im in need of a new motherboard for various reasons. I currently have a Core 2 Duo E6750. My question is since i only use my system for gaming/browsing net, would it be worth just buying a new motherboard like this (i want crossfire) or would it be worth spending something like £300+ for i5/amd. Would i notice a massive increase in spending this amount? Or would it be better to get the motherboard i mentioned and when needed getting a quad core like the Q6600?
