There is a version of the Sager (Clevo D900) that is out in the UK that has both i7 and SLI cards, but I'm not sure when it will be coming to the US.
Ok, nevermind. Wrong laptop. The one with dual 280's comes with mobile CPUs and is an 18.4'' screen. Intel's mobile CPUs are pretty much on par with their desktop counterparts. Any particular reason you need an i7?
