Crossfire question! :)

[sockky]

Hi guys, I am right in saying you can crossfire any 7900 card together?

If so, what would performance difference be between a 7970 crossfired with a 7950, compared to 2x 7970's? I'm intrigued.

I'm sure someone has possibly asked this question before, in which case, I appologise for opening a new thread.

Sockky.

I believe the 7970 would have to drop clock speeds down to the 7950 spec to work but don't quote me

Yeah you can Crossfire a 7970 with any 7950 or 7970, It will not clock down, both will work on their max clocks.

But I prefer to use the same card, same model and same everything.
That is why I have 2x 7950 MSI TFIII.

Well, if i do decide to get a 7950, it will be under water and reference 7950 has the same PCB as a 7970 if i remember correctly. So both cards will look the same

Hmmm. This is probably going to happen.

Thanks for the help both of you

If watercooling ensure you use same blocks for both cards. or it can make tubing a nightmare

Was planning on it, im far too fussy to end up with odd blocks!
