My question is: does anyone know if these cards will fit in the same space? How about heat... My case is the CoolerMaster with both front and rear fans, both side covers and top and bottoms are well vented...
Pretty sure my Power supply will be sufficent: 850W Thermaltake(quad sli/8800gtx sli compatible).
The cards are 11" instead of 8.5" They generate more heat too, but I don't think it will be too much of an issue. If you are talking about the Stacker 830 case then my only concern is cable length. You'll need to be able to run one of the 8 pin connectors and one of the 6 pin connectors to the bottom GPU. It's going to be a pretty good stretch but I think you can manage it. The PSU should handle them just fine.
@OP: I would take 1 GTX 280 over 2 G92s anyday because of the vram. It will make a difference at 1920 x 1200 in both of those games. I can almost run out of vram on my 8800GTX SLI.
