We've already been hands-on
with NVIDIA's first Kepler GPU, but all those fancy features count for nuthin' if the benchmarks don't back them up. So do they? Huh? Do they
? NVIDIA told us to expect a 10 to 40 percent performance boost from the $499 GTX 680, versus AMD's pricier Radeon HD 7970
, and it appears that was no exaggeration. If you've bought yourself a high-end 28nm AMD card recently, try to hold back those tears until you've glanced over the reviews after the break. Let's just hope for a fairer fight when NVIDIA's mainstream and low-end cards come out to tackle AMD's 7800- and 7700-series -- and hey, some timely price drops could help to balance things too.
