HD 7950 + 2x HD 7970

post #1 of 4
Thread Starter 
So I currently have two HD 7970s in my computer, and a friend of mine offered me a really good deal on his 7950, I have read that you can use any cards that have the same first two numbers can be used in a crossfire configuration. I was wondering if this still applied to trifire setups, as well as how this would affect my performance. How would this setup work? Do crossfire setups have to be clock-matched? Or does the system somehow use all of the power collectively? Any and all help is appreciated.

Will work, scaling will be a little worse, heat and power would be the big concerns going from 2 cards to 3. The biggest issue for now is the frame time latency, but you already deal with that with your 7970s in crossfire.

If you are only gaming on one monitor though it probably isn't worth it as you should be able to max your games and I don't think it will have a great improvement on the minimal frames per second.

I have a similar question with the same situation, so any 79XX version can xfire with a 7970 smile.gif how does that work its not the same power etc but combining it into 1 card?

I'm actually buying a 1440p monitor soon so I want to have my rig pushing 60+fps in as many games as possible.
