I heard this before but I can't recall if it'll work. Is it possible to use a factory overclocked video card with a vanilla or standard video card in a multiple GPU setup (Crossfire or SLI)?

you can use a OC card with at standard card in SLI/CF just as long they use the same GPU

limeDk is mostly right. As long as the GPU and the memory match, that is all that matters. Not speed. Normally the faster card will underclock to the slower one. Just make sure the memory is same size as well.

The memory does not have to match you can SLI/CF a 2gb with a 1gb card you will just be limited to 1gb

Ah OK, that really refresh my mind up. Thanks.

Next task, how to cope with a 3-slot Zotac GTX 470 Amp! card, or just wait till someone sells a dual-slot one :P

That is true with Crossfire, but not SLI. Unless nVidia changed something it has always been that they must match in RAM amounts.

Crossfire can get goofy with memory variances, not bad, but you won't get quite the boost if the memory matched. Ideally, for sake of safety (GPU/memory overheat) you'd like a card that can hit the overclocked version's specs without stressing, but that isn't always possible.
