Dual 580s in SLI or 2 5870s in crossfire

Best advice is to wait until the product is delivered. If CoD runs out of the box on either Xfire or SLI then it will be the first. Otherwise you've spent a large amount of money on performance you'll never see.

I currently have a single 5870 I purchased more than a year ago. My MB is a Gigabyte with 1 16X slot and 1 8X slot. If by some miracle CoD is xfire compatible AND a second 5870 makes a significant difference in the eye-candy I can run in real time - then I'll find a second 5870 and get a new MB.

I really don't believe that will be the case however. I hope I'm wrong.

S!

P.S. Running 16X or 8X makes virtually no difference whatsoever (around 3% iirc)
