IMHO i think as of yesterday the best single GPU card for gaming is the new 6970 that was released ... i ordered one

in a few weeks when the drivers get sorted out it will outshine Nvidia

there were some reports of testing going around the net that put them on apr ... but dig under the blankets a little bit and youll find
under stress the 6970 was better and that is with the rushed drivers that were barely acceptable ... within a few weeks and new drivers the 6970 will stand obviously alone atop the single GPU gamer market


* The above is my own opinion based on about 10 hours of research and reading take it with a grain of salt
