Can I pair an nvidia 6600 gt with a nvidia 7900 gt via sli?

[K3J51]

Hi all, I've got 2 cards, both Nvidia, one is a 6600gt (512 mb) and the other's a 7900gt (256 mb), can I pair these on a sli mobo? Originally had a pair of 6600gt's but burnt one out due to a fan failure, the 7900gt just kinda landed in my lap from a mate who didnt want it. If I cant then which do you recommend I stick with? As I've mentioned the 6600gt has 512 mb and the 7900gt has 256, from my reading around the 7900 seems like the obvious choice but someone elses opinion would be appreciated. cheers.

absolutely not. as ct1615 said SLI need same model card to get to work though you can mix the brand of the card

As long as you keep away from AA the 7900 should be almost as fast as the 6600 SLI setup.
Here is a handy chart:

If you do use the 7900, do not forget to update the video drivers as well.
