SLI Question

[nasero]

If i have say a 6800 and then i buy a 7800 can i use those two together in SLI or for SLI do both cards have to be the same model?

Thanks!

Both have to be same make and model.

You cannot now, but IIRC that is in the works. Personally, I've always thought that they got it right the first time with matched models, but time will tell if there is some cost/benefit advantage to this sort of a rig.

Alright, thanks for the replies.

I do not think that there will be. Either the 7800 would be held back by the 6800, or the 7800 would have to do more of the work (say 60%) while the 6800 does the rest (say 40%).

Not to mention in this scenario, the 7800 would have TAA, better shaders, better high res, etc..

For a guy with a 6800U adding a 6800GT he picks up cheap is where I think this might be benefit.
