ACCORDING TO BFG AND NVIDIA "NVIDIA LinkBoost Technology
NVIDIA nForce 680i SLI MCP automatically increases bandwidth when select BFG GeForce® graphics cards are detected." I think thats when i started to get bfg also because it has better cards than evga and xfx but the only thin i like about xfx is the card graphics and i hate the billions of ridiculous names it gives its cards. So according to the manufacturers BFG is the card you should be using if your going to game. nuff said
