I just got a DFI Lanparty UT nF4 SLI-DR mobo. The new 7800 GTX 512MB cards are huge and need 2 slots. If I decide to get 2 in SLI, which would be outrageous in performance and cost, would they fit in the board, and if so, would there be enough space for effective cooling with air and the stock coolers? I checked the forum posts and haven't found a post asking this. If I missed it, please give me a link. Thanks.
