Hello, I've been reading a lot about graphics cards here and there and I'm forced to ask the pros just for assurance ^_^;
Anyway, currently I have 2 Radeon HD 6850 on crossfire using Eyefinity with 3 monitors.
Im planning to upgrade these for something such as the Nvidia 580 or HD 7950 or even HD 7950.
My first problem however, like always is budget. Im planning to spend no more than $600. Maybe a little more if its REALLY worth it.
The second problem I found was that in order to use 3 monitors with the Nvidia cards, I need to have them on SLI mode. I'm not too familiar with this, but After using Eyefinity is hard to go back, so this is a feature I'm looking to keep.
Third, the 7970 or the 7950?. Some say the 7970, others 7950. Although according to PassMark 7970 scores better.
Forth, Power supply, I assume If I want to buy 2 580's I may need to upgrade my PSU. Currently I have a 750W. I'm really focusing on GPU upgrade only now.
I'm so far leaned towards Radeon, since my upgrade will be a single GPU upgrade, meaning I can buy a second one in the future and have some sort of future-proof. Whereas if I buy 2 580's or 680's I wont be able to go further since I need to buy 2 to use 3 screens...
This is my current build:

CORSAIR CAFA70 120mm Dual-Fan CPU Cooler
CORSAIR CMPSU-750TX PSU (80+ certified)

No it doesn't score less in games than the 580. It only scores less in applications that you would normally use a professional GPU because they limited it so that they can still sell their workstation GPU's.
The 680 is the fastest single GPU card out on the market. But do to availability you will have to wait a bit if you do want to get it.
If you need it today yes you can get the 7970 but it is overpriced. If you don't mind overclocking it then it should be able to perform close to the 680 but only once the drivers are updated so you can overclock to 1300.
