For the majority of us a single 3870 or 8800GT can handle most of the games we play with all the settings maxed out. The only super high-end app that could make a large number of people want to jump onto the multi GPU bandwagon is probably Crysis. The problem is, Crysis scales very poorly with multiple GPUs. The 1.1 patch was supposed to fix that and it didn't. So when the new dual GPU cards come out like the 3870X2 and the 9800GX2, everyone is going to read the review and go straight to the "Crysis Benchmarks" page where they will see sub-amazing performance. The quad GPU performance will be even less impressive. So without significant real-world gains, who's going to jump on the dual GPU card bandwagon? It seems less than compelling at this point.
I can tell you though, if Crysis scaled well with GPUs, I would no doubt go quad SLI with the 9800GX2. I just don't see that happening though, and my rig right now can handle any other game maxed out plus with AA and AF.
