Sorry - I didn't word this well. I'm not running an SLI setup - just bought an
sli capable system board to get the dual 16x slots.

Most graphics cards require a physical 16x slot. They can function with 4 or
sometimes even just 1 lane, but the power requirements and the size of the
card are limits. Some boards have a 4x slot that is open ended, but these
boards always have severe limitations on the types of cards since the slot
isn't designed to support high power draw.
Another solutions would be the Matrox cards - I was told the drivers work
pretty well and they produce a G550 in a 1x PCIe formfactor.
