I have been building a system to run high resolution for auto desk and video games. I was thinking dual ATI 6990. I do know they are money but I looking for great performance. My question is 1 good and is two in crossfire worth it?

What resolution are you running? Honestly, I doubt it's worth going with quadfire for you.

6XXX cards have great scaling in crossfire. But single 6990 is overkill for today's all games until you don't plan to use EYEFINITY.

So you are good with single 6990 if using a single monitor regardless of resolution.

just get a single, getting double 6990s is an overkill even for 3x 2560x1600

I was going for 3 moniters. All of them about 24in

from what i've seen on the reviews... the hd 6990 runs very noisy... are you sure you can live with that? if yes.. then sure 1 hd 6990 is the best choice....

if not.... you can try 2 hd 6950 crossfire... maybe it's not as fast as hd 6990... but it also cheaper and more value for money... and it should run quieter than 1 hd 6990..

I will be using these cards for video game design, and 3D animation.

Quite is not an issue as the system will have liquid cooling on the video cards

then 1 hd 6990 is more than enough to power your needs...

The drivers and extreme noise levels for a pair of 6990's in Crossfire make it highly likely that they would be a disappointment. You should read the threads about AMD drivers before purchasing a pair of Crossfired/quad GPU 6990's. http://forums.guru3d.com/forumdisplay.php?f=46

Also check out this article. Multi-GPU's don't even kick in on some of the games:

"Weirdly enough though, how do I say this right, I felt that the R6990 is the stronger performer, but the GTX 590 is simply better supported and runs a tad smoother at 5760x1200. In terms of heat and noise the GTX 590 will be the clear winner. And as stated, performance wise the R6990 is the frontrunner. Now then, the dark horse -- Quad GPU gaming with two cards is in favor for NVIDIA, the overall scaling is much better, and here again each team takes some wins and total losses."

For noise levels, you won't notice it while gaming if you got a good case.

6990 CF performs great for my single monitor. Will get 2 more for EYEFINITY when budget allows.

AMD driver team has worked real hard. I don't have any issue with these cards till now.

But the articles i read about 590 burning while overclocking and overheating which have really surprised me.
nVIDIA's new drivers for 590 downclock it which is simply UNACCEPTABLE.

Amazing how 90% of the people here only say ATI but they have been that way sine the 4k days -_-

ATI isn't the only game in town nor is anybody else.
