Just wondering if you can Sli different card types? I have a 7900GT and was wondering if I could Sli it with the 6600GT it replaced and still get a performance increase? (I'm guessing the answer is NO! btw) ;-)

Try it out! You never know worst thing that could happen is that you dont get a display

Eek! Don't listen to Nikalus! You cannot pair a 7900 GT with a 6600 GT because they are different GPUs. You can pair any cards together if they are the same series and version (e.g. 2x6800 Ultra, 2x7800 GTX). But since the 7900 and 6600 are two completely different GPUs you cannot pair them up in SLI.

Yep the answer is no. Gigabyte GA-K8NXP-SLI AMD Athlon 64 FX-55 Corsair 512X4 2048mb 2X WD Raptor 74gb 10K RAID 0 250gb WD Caviar 2X 256 6800 GT WinXP Pro X64

Yeah, it's a shame, would have been nice to use my 'old' 6600GT for a bit of extra speed. Second 7900 GT it is then (haha, not this month)

Sell the 6600GT. Many people would like to have it. "A bit of extra speed"????? Why isn't your 7900GT good enough? Is there a new game out there can use more than the 7900GT offers?

Haha, yeah, I thought the 7900GT would be good enough, then I installed Oblivion... Funny thing is I could have bought a 360 and Oblivion for less than the cost of the card. Oh well.
