Score
P8259 3DMarks

8903
Physics Score
7003
Combined Score
6489
Intel i7 930 @ 3.8Ghz
GTX 670 @ 1009Mhz Core 1074Mhz Boost Mem 3206Mhz (6412Mhz effective?)
GPU OC on stock volts on a stock Inno 3D
Seems decent?
A little low if I am honest. Have you tried overclocking it much? Looking at other graphics scores, you should be hitting around 9500 with a decent overclock.
