Theoretically the 6970s will dominate. I haven't seen benchmarks. However, with that much power you will learn the term bottleneck. Because of the bottleneck I wonder which would actually perform the best in real world?

4x 6970s will far out perfrom 2x 6990s, but 2x 6990s are much more power eficient... it realy depends on what he will be doing with them... any more then 3 or 4x 1080p, go with 3GB 580s or wait for new cards... unless he wants like constant 120 FPS with TN pannels, i would say got 2x 6990s... give us a better idea of what they will be used for and we can give you a better recommendation smile.gif

well we already have 2 older screens and he want the leftmost to be the primary display when he's not gaming, and plus we didn't plan this out very well.

I have a 3960x with crossfire 6990's. If you are going to be primarily using your rig for gaming I would highly recommend it over quadfire 6970's.

For example, in BF3 @ 2560x1600 all ultra settings, 4xmsaa, 16x anistropic filter, HBAO, I average around 100-120 fps outdoors on huge maps like Wake Island, and 120-160fps indoors. This is on stock clocks as well. I also don't ever notice Microstutter either.

Of course, the quadfire 6970's would be much better for benchmarking and huge eyefinity resolutions.

I went with the 6990 crossfire because I my LSI raid controller uses an 8x slot, so quadfire 6970's or 580's is out of the question.

thanks people, we decided on the 2x6990, because of the issues with heat and his psu, plus we got a deal on the 6990s.

How am I supposed to know that when there was no previous evidence of what you said to even be in the original post?
