With an SLI motherboard, can you use two different PCIe cards if they are not in SLI?

I want to use one PCIe 7850GX2 nVidia card for primary graphics, and one PCIe ATI All-in-Wonder X600 for multimedia.

Will this work?

Can't seem to find the answer in Google; probably not wording my search right.

Thanks,
Glendor...

you are definetely going to have problems with the drivers. 2 nvidia or 2 ati cards would work just fine.

In a way, that's good news. Drivers problems can be experimented with, and may (or may not) be resolved. I was afraid that putting two non-matching PCIe video cards in a SLI motherboard would cause a meltdown, or something just as bad.

Anybody else have any ideas about this idea of mine?

It will work with XP with some potential driver difficulty. Vista does not support using multiple display adapters that use a different WDDM driver at all, so in that case you would not be able to mix ATI and Nvidia cards.

Okay, so it sounds like it's possible if I stick to WinXP, and I would have better luck if I use ATI for both cards.

Thanks for the advice.
