in single card set ups. Xfire gives more benefit than SLI atm, however, and shifts that list more towards ATI's benefit in multi GPU set ups.
I'll agree with that for the most part, except for your last comment.

Scaling looks pretty good from the Radeon HD 3850, however it's still not as good as what NVIDIA is able to achieve with the 8800 GT. NVIDIA consistently achieves about 11% better scaling from one to two GPUs than AMD.
