Gigabyte X58A-OC Sub Zero Review
3D Mark Vantage
Naturally there isn't really anything we can compare this too, so our results today are more of a comparative indication of things generally. The extra two cores and 1.6 GHz only improve the GTX590 by 4300 points of P-Score, showing that even at these medium settings the GTX590 isn't exactly CPU limited. In 3D Mark Vantage anyway. 43000 from a single card is pretty spectacular though.
In case you ever wonder how your setup compares to something as stupendously expensive and overclocked as this 990X/GTX590 combo, here is the 3D Mark Vantage screenshot.
