Swapping my 2006 Mac Pro 1,1 for a 2012 Mini 2.6Ghz Core i7 & Fusion The Mac Pro had 2x OWC 256G SSD's & ATI Radeon HD 5770. Each with 16GB. In Parallels, the Windows 7 Experience Index on the Mac Pro was 7.1, 7.1, 6.8, 6.8, 5.9. On the Mini, it's 7.6, 7.6, 5.9, 5.2, 5.9. The Mini doesn't have the "3D business and gaming graphics performance" of the Mac Pro 1,1 w/5770, but otherwise it fares pretty well. Also the Mini is using ~37W -vs- ~260W for the Mac Pro, and dumping a LOT less heat into the room.
