Can I run a pny 7900GS and a xfx 7600Gt in sli mode?????

[imported_goldlight]

I just got a killer deal on a pny 7900Gs.
I already own a xfx 7600gt xxx.
So of course...Im greedy and I want to know if
I can run these in sli mode?
Can I over clock them both to the same specs????
Help please...I'm having a fever with the thought that I could possibly
have my first sli experience.

No.
They have to be in the same family
i.e. 7900GS with 7900GS. It doesn't matter what brand or model number, just that they are both 7900GS's.

So no, it won't work.
