You can buy a 4gb version of the GTX 760 if your budget allows that. I think that Nvidia has better multi screen support, especially if you might drop another card in later for dual sli. The 760 is also a newer card, and there pretty much the same performance wise. Right now, at least, AMD is having problems with crossfire and eyefinity together. I think either card would do fine, but there is different setups for Eyefinity and Surround. Just make sure you get higher than 2gb VRAM.
