Has anyone using the GTX-590 or AMD 6990 with CoD?

[*Buzzsaw*]

Salute

We all know that dual cards in SLI or Crossfire are poison for this program.

Which means those with multiple monitors are caught between a rock and a hard place.

The usual solution of dual cards won't work.

The only other solution is the new dual core graphics cards from AMD and Nvidia, the 6990 and GTX-590.

These cards have the negatives of high cost and noise, but deliver huge, 4 Gb and 3 Gb multiple monitor performance from one card.

The 6990 seems to have better performance, but is quite a bit noisier, both cards run about the same price.

Wondering if anyone has had any experience with these two options?

Do they work with the program? How do they work with the game in multiple monitors?

Any info would be appreciated.
