I've been thinking about the Mac Pro but noticed that the video options
available are pretty much at the bottom of each of their respective
categories. Is the video upgradable via any off the shelf PCI-e card or
does one have to buy a special "Mac" version? For instance, would an
nVidia 8800 board work fine in it.
For that matter, why does Apple sell memory upgrades at twice the price
Kingston does?
