A new firmware discovery in the build of Mac OS X 10.6.4 for the new Mac mini, as well as a set of leaked NVIDIA drivers, has suggested that Macs will have Radeon HD 5000 and GeForce 400 graphics in the near future. The ATI-oriented code doesn't identify any chipsets by name but does at least appear to run an aftermarket Radeon HD 5870 on a basic level through some extra work. Others trying to use a Radeon HD 5770, and Mobility Radeon HD chipsets, aren't having the same success.
