Stupid question about SLI motherboards.

[johnqinternet]

I was wondering if you could use two different cards on an sli motherboard. For example a low end Quadro in the top slot and Geforce 6800 on the lower slot. I want to know do the sli motherboards only like the same cards to be conected in sli mode. If anyone here has a setup with dissimilar cards tell me if everthing works okay. I am asking because I am looking to buy a DFI LANPARTY UT nF4 Ultra-D. Thanks in advance

EDIT: What I meant to ask: Is it possible to buy an SLI motherboard and not use SLI, just use the motherboard to connect 2 completley different cards. Like a X800 and a Geforce, or Quadro and Geforce or any other combination.

You need identical cards.

You need identical cards to use SLI.

I'm not sure, but I think it is possible to run two different cards on an SLI MoBo, but the only reason would be to run multiple displays. They wont improve graphics performance at all.

Ideally I would like to build a system that would get good perfomance at both 3d apps and games. Geforce cards do not do well in 3d apps. I looked into softquadro mods, but nvidia might put security measures to prevent softquadro in the future. It would be nice to have the option to put both kinds of cards in the same system. I could then select wich display adapter to use in which app, or disable one of them and enable the other in the Windows hardware profile and use a KVM switch. Any way I am not sure how this would work and I might have to use KVM switch no mater what.
