Mac Pro users are all about kicking things up a notch -- after all, they’re the last current Mac available with expansion ports, so why not take advantage of them? If you want to truly go nuts, NVIDIA now has a graphics card just for you.
With this week's refresh of the iMac and Mac Pro line, Apple chose ATI graphics cards, no longer offering even an option of NVIDIA graphics. There's a lot of rumors as to why Apple made the switch to ATI-exclusive graphics, but new speculation leads to believe that Apple was able to achieve a larger graphics performance boost from the ATI cards instead of NVIDIA cards.
Whether it was through neglect or indifference or a market focus elsewhere, certain kinds of gaming have long been a PC-dominant endeavor. iPhone game app sales likely helped draw some attention to Mac users' game lust. So it was a pretty big deal when Valve announced Steam was coming to Mac users everywhere. Now according to a Valve employee, those desires are going to be stoked even higher.
