My choice for a graphics cards for the next generation of iMacs. The ATI Radeon HD 4850.

The only issue I see is with the power consumption. Wonder if the iMac can supply this kind of wattage. They have Linux drivers from the day of release and are releasing specs for open source driver development.

    The iMac uses all-mobile GPUs, and the Mobility Radeon HD 4850 is rumored for late Q3 or (far more likely) sometime in Q4. Should be able to play almost all games at high quality at 1920x1200.

    What drugs are you on?



    That is for the Mac Pro, if any system.

    Apple doesn't call them mobile GPUs, but they are. The chip Apple calls the 8800GS, is actually an 8800M GTS, which is quite a bit less powerful than the desktop 8800GS.



    *slightly off-topic rant*



    Nvidia likes to play name games with mobile GPUs, to make people think they're better than they are. Of course, the desktop GPUs are often unsuitable for mobile use, and have to be cut down quite a bit to meet the heat and power requirements of laptops. But the drastically cut down versions have the same names as the "full" versions, making it almost impossible to directly compare them.



    ATI doesn't do this. The Mobility Radeon HD 3850 has the same 320 stream processors as the desktop 3850.

    Same number of stream processors doesn't automatically mean same performance. The mobile parts will have slower core and memory speeds.

    Yes. They're certainly lower clocked.
