Based on performance alone, it seems like the Mac Pro addresses a smaller market each time a new iMac appears. But there remains a need for a highly configurable and fast performing Mac. The new Mac Pros may be little more than speed bumps from the systems they replace, but they do offer better performance at the same price, while offering even more options for customization. Whether your type of work requires a certain kind of display, add in card, or tons of internal storage, the Mac Pro offers power users the flexibility to create a system custom fit to fill their needs.
