ATI hasn’t yet implemented the CrossFireX support to the Eyefinity technology; consequently, it’s not yet possible to take advantage of more GPUs in the moment that games are executed in more than one screen with surround gaming, and thus not using all the power the system has in that case. Perhaps with future drivers, ATI will overcome this limitations. nVIDIA has done so already, indeed, it’s not possible to have the surround gaming implemented without the SLI technology at all.

This makes us think that perhaps the 3D Vision Surround technology was developed by nVIDIA as a proper response to the Eyefinity from ATI. Two points lead to that conclusion: one, the necessity of two cards in SLI with the GTX 200 cards, and the lack of support for more than two displays on the GF100 for each GPU.
