I've been seeing a lot of warnings that two-slot cooler cards (2 of them in SLI that is) will not fit in and mobo but the A8N-SLI. this seems like rubbish to me. why would gigabyte, DFI, MSI, and others make mobos that cant support 2 6800 ultras. its insane. i understand that with only one slot in between the two x16 connectors, they wouldnt have much breathing room, but they would fit and work just fine, wouldn't they? someone clear this up for me, because im considering a leadtek PX6800 GT (two slot cooler) in a DFI SLI-DR, and i want the opportunity to upgrade to SLI combo in the future. ??????????
