I am going to build a solid workstation with a MacPro 5.1 for Izzy and the question is...  which GPU to use for 4 outputs in 1080p?

I have a Matrox TH2Go DP ... absolute fail - no Full HD support on my MacBookPro (Thank you Matrox) for 3 outputs :-(

What's stable and powerfull enough to play on 4 FullHD displays (projectors)?

This one's look good, but what about GPU (OpenGL, OpenCL) acceleration for Actors?

• NVidia Quadro M2000, 4GB GDDR5, 4x DisplayPort
• AMD FirePro W7000, 4GB GDDR5, 4x DisplayPort

... or is it better to use a consumer gamingcard with Titan or Pascal GPU?

There is also the Blackmagic Decklink Duo 2... it's complete without acceleration... but with the benefit of inputs...

So whats your opinion... Thank's a lot...

Tom
