Weve learned that dual GT200 cards have been sampled and you can even see some pictures on Chinese Web magazines. It is a dual, sandwich board design, an approach that Nvidia fancies for a while and naturally, the card should end up significantly faster than both HD 4870 X2 and Geforce GTX 280.
The board will draw a lot of power and it will be hot, but at the same time, it might win the performance crown back from Nvidia, and Nvidia is desperate to get it back. Nvidia simply doesnt know how to work as an underdog and this card and a new driver for GTX 260 are actually dramatically changing the odds.
At this time, we are not aware of any faster HD 4870 X2 card that might come to jump on top of dual GT200 55nm, but we wouldnt completely exclude the possibility.
Sources also confirmed that in order to see the real power of dual GT200 55nm sandwich board you would have to use 1920x1200 with all settings on, or preferably 2560x1600 30-inch resolution, something that few can afford these days.
