Really awesome systems everyone!
I did quite a few changes lately as I pretty much stopped playing games and focused more on iRacing.
As I moved my displays, I had to, unfortunately, sell the Mac Pro. The Retina MBP replaced it before anyways.
As iRacing is not yet all that demanding, I have no future upgrades planned.
I'd love to get a USB 3.0 equipped and thinner Thunderbolt Display for my Mac though!
