Intel Mac minis' sports integrated graphics card
If you are interested in getting yourself the ultimate Mac gaming machine, the Mac mini has never been for you. The new Intel Mac minis are much faster, which might make some Mac gamers think twice, however, as Joystiq points out this iteration does away with the stand along graphics card. Instead of having a stand alone graphics chip with its own RAM,
the Mac mini now has an integrated Intel graphics chip which shares a minimum of 80 megs of the system's memory to operate.
This was probably a cost cutting measure, but I think it might have been a mistake.
