Hey folks, I bought an iMac last week as an all-round computer, and it's a good one. No doubt. But for those of you intending to use Boot Camp for gaming (through Steam, in my case), a word of caution: I've been having performance problems (some of them insurmountable) with several games that I've bought from Steam. These games worked fine on the 2009 Mini that my new computer replaced, using the exact same OS, so I contacted AMD to ask whether there were any known issues with their current drivers for the Mobility 5850. Here is the reply that I received: Thank you for the response. However we no longer manufacture the graphics card. We only provide the Graphics chip to our partners such as (Apple, Visontek, Diamond and Sapphire). Apple and their partners manufacture the graphics cards and write the Video Card BIOS and Video Card BIOS which is offered only through OSX updates. For further information please contact Apple. When the day comes that I'm relying on Apple to make a graphics card work in Windows, I know I'm in trouble...! Anyway, the bottom line is that AMD appear to have washed their hands of this graphics card. Certainly, they're not remotely interested in offering technical support for it. I'm gonna get back to AMD now and appeal to their sense of corporate humanity. Wish me luck.
