6950/6990 crossfire

post #1 of 7
Thread Starter 
i just ordered a HIS 6950 which i believe can unlock shaders, or even to 6970
http://www.newegg.com/Product/Produc...-355-_-Product


would it crossfire with a 6990? do i have to unlock to 6970 in order to do this?

psu calculator reccommends this rig have 468w, then id need another 375w for the 6990, summing up to 843/850w. what do you guys think?

Yes you can, and I believe your PSU can handle it.

Wait so you can crossfire different cards in the same generation in any situation? 5850 + 5870? 6850 + 6870?

What about Nvidia? 460 + 480?

Same generation, same chip set only ATI. Like barts pro can go with another barts pro. Cypress XT goes with a Cypress XT. Must also be of same generation. But nvidia can't do that. and you can't do a 6850 + 6990.
