I have noticed that many people here claim that crossfire scales better, and that HD3870 crossfire performs better than 8800GT SLI. And all those claims are based on one old review from experience.com
I have now a more recent benchmark that use a newer drivers, and it proves that 8800GT SLI is better than HD3870 crossfire
Here is the review
AMD's Radeon HD 3870 X2 video card - The Tech Report - Page 6
Note: This is a review for HD3870 X2, but it also shows how two HD3870 in crossfire performs against two 8800GT in SLI
