I wanted to upgrade my cpu and needed some help. Will I notice a difference in gaming if I upgrade to a 3800+. Core 2 duo is out of the question, since I dont have that cash on hand to buy new ram and mb and a really expensive cpu. Is it a better buy to just buy a 4200+? I dont plan at overclocking at all, since my motherboard is horrible at it. Should I just stay with my current cpu and upgrade later. I currently have a 7800gt and its been great, but I think my cpu is starting to bottleneck it in some newer games.
