That MSI Lightning GTX 580 is a very nice card. Quality built puppy. I'm sure that will OC very nicely. Congrats to the OP, sweet arse card.

Well performance wise two AMD 6970's will be better than one GTX 580 where two cards can be utilized.
Unless you SLI down the road, then two GTX 580 will be better than two AMD 6970 in crossfire. Your PSU is capable of either choice. You can get an AMD 6990 and crossfire it with your AMD 6970 for some what about the same price of two GTX 580's also.
I seen your monitor is at higher res. If your only going to have one monitor you'd be fine with the GTX 580 1.5GB instead of AMD 6970 2GB. If your planning on two or more monitors at that resolution then the AMD 6970 would be a better option to keep and crossfire. Instead of 3Gb you'll have 4Gb's. Your half way there already.
Up to you, and your thoughts for down the future.
I'm down the 3D movies and 3D gaming path, so GTX 580 was my best choice. I may or may not SLI it but no need to at the moment, I'm already maxed settings in games without any issues. Spent quite a bit on this new rig already since December. Beside I kinda like one card solution at the moment not having to deal with any issues that sometimes comes with two cards and drivers.
