It it possible to SLI an 8800GT with a 260GT? If not, do the newest models support mixing models in SLI?

Edit-
I was wrong, just done a bit more research and tried it here on a spare machine and some stock cards I have on the shelf.
If you try multiple cards from the same generation - 7x series, 8x series etc, it works at the speed of the slower device.
If you try multiple cards from different generations - a 7x series with a 8x series, once it worked but the second card was simply dead and displayed nothing, in a different configuration, it just won't display anything on either cards.
I can confirm that nothing is broken and both cards work fine, so you have nothing to loose by trying it, however based on what I have just seen, it will only work if you use two from the same generation.

1I've always seen that the GPU core has to be the same for SLI, but vRAM could be different and only the smallest common amount would be used. Do you have a link to where two completely different models can be mixed in SLI?– MDMarraOct 7, 2009 at 11:27

That's too bad, I haven't been keeping up on SLI, I have hoping they had finally introduced hybrid SLI like ATI has with crossfire.– MDMarraOct 7, 2009 at 14:51
