MacRumors on rumoured new ATI cards for our Macs:
Mac4ever (french) received word from ATI that while the Radeon HD 4870 X2 will not be coming for the Mac, ATI has confirmed that both the Radeon HD 4870 and Radeon HD 4850 will be coming for the Mac “soon”.
For those interested in benchmarks, AnandTech provides an extensive testing roundup of the two cards with benchmark comparisons to the ATI Radeon HD 3870 which was released for the Mac Pro in June.
I’m still waiting on a 3870 from ATI. The 8800GT doesn’t perform well in games for Mac OS X, but is very powerful in Vista and XP.
The best place, as always, for Mac benchmarks is Barefeats.
