I think maybe it was [H] who had (or linked to) a setup like that not *too* long ago. Might want to check it out. IIRC, the 2x6600GT held it's own quite well against a 6800GT, sometimes slightly passing it. Whether or not it's cheaper, worth the money for a dual PCI-e board, etc, I don't know.
I don't see enough of a gain (if any) to want me to go with SLI, seems smarter to just buy one 6800. What I wanna see is 6800 SLI, is that even possible yet?
