Can I run two nvidia 660TIs in two-way sli, one as pci 3.0, the other in pci 2.0

[Carson Folk]

I have this mobo that has one pci 3.0 with a 660TI in it and I was wondering if I could put a second 660ti in the pci 2.0 slot and sli the two?

Yes that would work fine. Do you know what the second slot is running in? My Board has a 3.0 and 2.0 but the 2.0 x16 is running on x4 mode. If both are x16 slots it would work fine.

also, how is the performance when one card is running at x8 or x4 (the pci 2.0)

Ok, good board. It supports SLI well. When running 2 card ( SLI ) on this board, both of them will run at PCi-E 3.0 x8, equals to PCi-E 2.0 x16, so there won't be any loses in terms of performance. Just make sure that your PSU has enough power cable for those cards and you're good to go.

Yep, everything should run good!
