It looks like Mac Pro users wanting to get in on some of the latest and greatest action without ditching their old system altogether are still out of luck, despite a recently released “upgrade kit” from Apple that got some of their hopes up, and caused some consternation for anyone that actually took the plunge on one. As a number of users have reported on various discussion forums (one of which is linked below), the $349 GeForce 8800 GT upgrade kit only works in the newest Mac Pros, and not the older models, due to their lack of support for PCI-Express 2.0. That little detail was indicated as requirement by Apple, although many apparently assumed the cards would work considering of the inherent backwards compatibility in PCIe 2.0. As you might expect, many users are none to pleased with Apple actions on the matter, with some claiming that the company’s interested only in getting customers to buy a new system instead of prolonging the life of their old one. Shocking, we know.
