nVidia GTX680 Review
3D Mark 11
We all know that there is one number you're all interested in and you can see that the GTX680 just edges out the HD7970. When overclocked things tighten up dramatically. The GTX680 giving 3507 X Marks vs 3521 for the overclocked HD7970.
Compared to the GTX580 it's 33% quicker, which is a monumental increase.
3D Mark Vantage
In Vantage things are, again, very close indeed between the two flagship cards. If this is an indication of what we can expect in gaming tests then this will be decided on points.
