"Based on Catalyst driver 8.790.6.2000 (8.79.6.2 RC2) given to press, the Radeon HD 6970 delivers approximately the same performance as NVIDIA's GeForce GTX 570. Recently launched at the $350 price point, the GeForce GTX 570 and Radeon HD 6970 go back and forth between tests but at no point does the Radeon HD 6970 ever approach GeForce GTX 580 performance levels. According to AMD this won't occur until Q1 2011, when they unveil the Radeon HD 6990 X2 video card. Featuring dual Cayman GPUs, the codename 'Antilles' produce line will replace their aging Radeon HD 5970 video card. Unfortunately, missing the holiday shopping season could prove to be a deadly mistake for the AMD graphics team. "

所以6970現階段只能跟570打平??
