580 sli is fastest, 6950 crossfire is far better in terms of price/performance. Some people will say the 580 sli is best, others will say the 6950 crossfire is best.
If you are buying either, you'd want an intel cpu.
Oh and money isnt a problem plus if im getting those i would get a I7 2600k even though i dont overclock
Or a I7 3930k even though they are a bit overkill its much more future proof
