Sounds like more bloatware drivers from NV. If only they could get their drivers to work correctly without issue. I could care less about SLI, I just want my single 8800GTS to work properly. When an update to drivers make NeverWinter Nights fail with your brand new 8800GTS you know they suck. I'm sorry, but if you're willing to trade stability and applications for a few more FPS in the lastest crap shooter then I'll take the competition's offerings instead.
One 4870 from ATI trumps most SLI setups, and the 260/280 setups that it doesn't aren't worth putting in SLI. Either before or soon after Xmas something else will be out that will stomp on the SLI of today.
SLI was a marketing scam from the start and offers little advantage, unless of course you consider a high energy bill from having to cool your computer room even in the winter a benefit. Or if you actually enjoying having to purchase a costly monitor so you don't look like a fool with two cards in your rig.
