Even if they were never upgradeable.. that's not a huge deal breaker for me. I used to upgrade vid cards often... but not anymore. The card I have now in my MP is the stock card. Granted, I upped it on order to the better version... but still... these cards look to be very sufficient for a long time.

Not only does it feature a state-of-the-art AMD FirePro workstation-class GPU with up to 6GB of dedicated VRAM — it features two of them. With all that power, you’ll be able to do things like seamlessly edit full-resolution 4K video while simultaneously rendering effects in the background — and still have enough power to connect up to three high-resolution 4K displays.

Up to 12 GBs of Vram.... cool
Heaven forbid we should have to rely on the 12 core CPUs or the Ram for any lifting... laugh
