WoW is very dependent on your video card, and plays rather poorly on Macs using the Intel GMA video architecture. Part of that is due, however, to the rawness of the MacOS X drivers for Intel video. If you set up Bootcamp on that Mac Mini (intel), you'll get much better performance under Windows.
However, for intel Macs with GPUs such as the Radeon x1600, performance matches similarly configured PCs (smooth like butter on my 20" iMac)
