ok so built my buddy a computer with some high end equipment in it and then performed 3dmark11 extreme test to see his scores. Then just for shits and giggles i ran it on mine to just to see how much of a jump his was over mine. the results are boggling my mind i dont know how they could be accurate.
2600K OC to 4.5GHz, G Skill ripjaw x series 8 gigs , evga 570 GTX OC, asus p8p67, 64 G SS drive, 2 1T hard drives raid 0 and 650W power supply
Q6600 OC 3.2GHz, GA UD3P mobo, 4 gigs ocz reaper ram, 570 GTX, 2 150G raptor 10k rpm hard drives and 1000W PSU
my score: 1805
What OS is each of those comps running? The Sandy Bridge comp might have tessellation enabled while the Core 2 doesn't. This was also done at the same resolution, right?
Those are the only two things that I could think of that might affect it.
