Oolite Bulletins

The new iMac is claimed to be the most powerful iMac ever with a choice of ATI Radeon HD 4670 or 5670 cards.

Whats the betting that Oolite won't be as good with these cards as with the older Nvidia cards?

Looks like a nice machine though.

Oolite won’t be GPU-bound on any of them under anything approaching normal circumstances, and the Mac OS X drivers for ATI hardware don’t suck, so I doubt there would be an appreciable difference.
