I'm talking about On the level of PC gaming. I'm not sure if its easy to upgrade the latest video cards on Mac pros and if most are compatible. I will buy a new Mac Pro this year when they come out and I'd like to be able to do this sort of thing. I like macs and OS X that's why. If not ive been thinking about building my own gaming PC but I hate windows lol (I run it on my mbp to play some games) and I'd rather not have 2 towers in my room. I already have 2 tvs in there and all my gaming consoles take up a lot of space. I have more uses for the Mac Pro. I'd use it for everything.
