Has there been any technical details on Nvidia's Maxwell and Kepler graphics card series?
The Kepler allegedly has roughly 16 times the performance of the current Fermi cards. You could play Crysis on 2560x1600 with 16x AA with only one of them!
What about the ATI HD 7xxx and 8xxx series cards?
slow down man. nvidia still not finish with with Fermi yet. btw kepler should be 4 times faster than fermi not 16. that is for maxwell compared to current gpu. however when nvidia mention 4 times performance increase i don't think it refers to gaming performance. more likely it is DP performance which is related to their Tesla cards. about AMD next gpu some rumor suggest it might come out in Q2 2012
