does it work to CF 7950 and 7970?

Solution


No the same gen, just the same TYPE.

OP yes they are able to Xfire, but the HD7970 will be slowed down by the HD7950. I would suggest you just stick to 2 of the exact same cards.

It won't be slowed down, but you won't get the same performance as if you'd xfired two 7970's. So if you own a 7950, yes you can xfire it with a 7970 and get better performance in most games than a single 7970. It will also perform better than two 7950's xfired.
