We've been waiting for the mainstream-oriented Nvidia GeForce GTX 660 Ti to hit the shelves since we first saw the Kepler architecture way back in March this year. As is its wont Nvidia brought the top-end GeForce GTX 680 out first, aiming squarely at AMD's top GPUs, and to start with had the edge.

As time has moved on though the AMD Graphics Core Next architecture, exemplified by the excellent AMD Radeon HD 7970 GHz Edition, has proven to be a tough nut to crack. As the AMD driver sets have matured and more Compute-focused game engines have emerged, such as those powering DiRT Showdown and Sniper Elite, the Radeon cards have taken the ball and ran with it.
