MSI went to 660 MHz, EVGA to 655 and XFX has now announced a card clocked at 675 MHz. The GeForce 8800 Ultra 768MB DDR3 RoHS Dual DVI XXX should be available sometimes next week. We don’t know the price yet, but we are sure it wont end up being cheap.
With the memory clocked at 2,300 MHz and the Shaders running at 1,667 MHz, it should be among the fastest, if not the fastest card around.
The whole spec of the card is here.
