2 HD 6950's vs. HD 6990

I'm planning on getting a HD 6990 and am wondering how they compare to two HD 6950's. Which setup will give better performance and by how much? Also, if I get a 6990, if I want to upgrade, is it a good to buy a HD 6950/6970 to go along with it?

Do not upgrade from 2 6950's to a 6990. Another option is buy a 6990 and just add it to your current crossfire setup. Have fun with quadfire!

Whats wrong with your 6950s? robertoenrique

My computer actually died, so I'm just trying to get an idea of what kind of performance I'll get if I get a 6990. I'm also considering a 6970 and a 570.

Like I said, my computer died... so I need to get a new graphics card. I'm not taking 2 HD 6950's and throwing them out the window. I had defective parts and had to return the cards, so I'm wondering what kind of performance i'd get with a HD 6990 in comparison to two 6950's
