Except for your L2 cache being 1/6 the size of the E8600, and only 4 way associative vs 16 way, yours has a faster clock speed @ 3.46MHZ vs 3.33MHZ. But the E8600 also has a faster memory controller. So it would be hard to make a 1:1 comparison. Your L2 cache is what really hampers it in gaming compared to the C2D CPUs.
