The GTX560, specifically the version we have on test today, the Gigabyte GV-N56GOC-1GI has features which you would expect for a NON-Ti card. As you will see on the specifications page of the review, the GTX560 has less shaders than its ti sibling but matching those of the GTX460 (336) yet thanks to the engineers at Gigabyte, this OC (Overclocked) edition has a core clock speed that's slightly higher than the stock GTX560, weighing in at 830MHz on the core coupled with memory clockspeed of 4008MHz on the 1GB of GDDR5 paired with a 256-bit memory interface. Moreover, this is a big increase over the GTX460's 675/3600 GPU/memory speed offering. How this translates to real world performance thought we will have to wait and see but at a glance it appears NVidia have indeed specified this card to perform between its stable mates.
