AMD announces the 7790, supposed to be ~20% faster than the 650ti.
ROUND 1, DISCUSS!
Doubt their estimate will be acurate until the drivers mature a little more. But they need a winner in the sub $150 price range because the 7770 is garbage.
Well, in all fairness, the Radeon 7770 is a much better alternative than buying a GTX 650 (non Ti.)
