nVidia GTX780 Ti Review
3D Mark 11
At stock the P score of the two heavy hitters are almost inseparable, but the GTX780Ti is nearly 500 points better in the Extreme preset. Overclocking, which is free performance remember, moves the GTX780Ti into an entirely new sphere of excellence, improving by 2000 points in the P-Score and 1500 points in the Extreme preset. To put that in perspective, that's 500 points better than a GTX690!
