ASUS nVidia GTX590 Review
3D Mark Vantage
Straight out of the gate the GTX590 leaps to the top of our single card charts and isn't a long way behind the GTX580 SLI setup. The main contender of course is the HD6990 and it's leaps and bounds beyond that. However, don't get the bunting out just yet, Vantage is notoriously generous to PhysX cards.
3D Mark 11
Sure enough once we move onto the more shader based 3D Mark 11 the GTX590 drops behind the HD6990, even when it's overclocked.
