Hey in a couple months I might buy another 7300GT from Apple (their kit) for my mac pro. When it comes, it'll be just the baseline 2.0GHz w/ the BT module installed. I got it for gaming purposes, along side a Mac desktop (replacing my 2.7GHz G5).* I know both would work fine in Mac OS X, and would they also work under SLI in Windows? What card would the performance be comparable to?
