I currently have a C2D e6600 OC'd to 3.12ghz and I was wondering if i would see noticeable improvement upgrading to a new board and CPU(i7,i5 or Phenom II). This is assuming the the video card is not a bottleneck. The performance gain in question is related to just gaming. I play current games like BC2, SCII and Just Cause 2. I looked around online and found the answer to be minimal gain but I wanted to see what anyone else had to say.
