Okay, a bit behind the times. So I picked up a 27" LED nonthunderbolt Cinema display for cheap - hooked up to one thunderbolt 2 port, the other one has my old 'big' monitor, also 27" with the same resolution. So now with the MBP itself, I have three 2560x1440 monitors. Nice.
The old hackintosh is now running windows 10.I'm using it as my 'word' machine - I want consistent formatting, I've had bad experiences when interchanging between Mac and Win versions.
