run two different sli cards??

[supercross99]

I have a single XFX7800gt (450/1050) and was wondering if I could just go ahead and buy a evga 7800gt and put them both in an sli setup?? I know the clocks are different on them but is this do-able? Thanks

UPDATE:
Thanks to AireWolve for this find. [From slizone.com]

Can I mix and match graphics cards?

In order to provide optimal symmetric scaling, SLI Technology requires the NVIDIA GPU to match. For example, a GeForce 7800 GTX must be paired with another GeForce 7800 GTX. Likewise, a GeForce 6600 GT must be paired with another GeForce 6600 GT. However, using the latest Release 80 Graphics Drivers, NVIDIA GPUs sold by different manufacturers can be used together in SLI Mode. For example, a GeForce 7800 GT from vendor ABC can be matched with a GeForce 7800 GT from vendor XYZ.


Can I mix and match graphics cards is one of them is Overclocked by the Manufacturer?

Yes. A GeForce 7800 GTX that is overclocked (for example BFG GeForce 7800 GTX OC) can be mixed with a standard clock GeForce 7800 GTX.

It shouldn't be possible with different brands and different clocks would make that a definite 'no'.

But if you flash the lower clock card's bios onto the higher clocked card, then it might be possible. Be sure to backup though.

Has anyone tried this out??

I dont know 100%, but I thought the newest nvidia drivers allow for different brands of cards....but I might be confusing it with crossfire.

Wow! Things really have changed.

You shouldn't have any problems if you use the latest '80' drivers. Different brands & clock speeds don't matter. I learn something new everyday.

Awesome! Nice find.... thanks AireWolve! The whole reason I asked was because I've got somebody trying to sell an evga model and was not sure if it would work together with my xfx model.

holy cow, I thought I read that somewhere, but many still think it isn't possible. Glad to finally put that topic to rest....and to put my mind at ease about picking up another 7900Gt in 8-12 months.
