Paul is a full time editor with a Mac Pro and he really needs to upgrade the video card. Leo says that he was very disappointed with the "trash can" Mac. It seemed pretty impressive, but it wasn't state of the art. The dual ATI Radeon cards aren't up to date and there isn't an upgrade path to beef them up either. He can attach stuff though, through dongles.
Leo feels that since Apple hasn't announced any upgraded models, that Apple has abandoned the professional market. That's why Leo went to Dell and bought Precision workstations. As much as Leo hates Windows, he's sad to say that going with a PC is really his only option moving forward.
