Hi all, I've finally figured out my perfect set up for the moment. After lots of research here for Mac Pro gaming and exploring the possibilities of running Windows 10 via bootcamp and possibly a NVIDIA GeForce GTX 1080 Ti as an external GPU...... I just decided it was way too much money and effort to put the square peg in the round hole. With the "PBP" feature in the 49" Samsung CHG90, you can not only switch between inputs... you can choose inputs for a split screen. Anyway, for me, this worked out to give me the experience I wanted for a 'best of both worlds'.... rather than just speccing out a high-end Windows gaming PC. Cheers!
