Dbl post, as it is simply intriguing enough to be a post on its own, and doesn't need to be garbled amongst the above musings
G3D has finally been allowed to publish their 2x 9800GX2 Quad-SLI testbed results.
Definitely some gains in HD>UHD(50fps in crysis at 2560 x 1600, and a fully maxed COD4 which apparently knocked the reviewers socks off at 1600p), but is it worth the phenomenal cost? no freakin' way!
Also, in the higher end games the quad doesn't do much better than the single 9800GX2. Sure, stable Q-SLI optimised drivers and games dont exist, let alone games that are tweaked for it(or x64 for that matter)

Multi-GPU gaming is the future, but not in this expensive getup. The quicker we can do away with mega expensive discrete cards, the better. Fusion+Hybrid is the answer, IMO
