Hi I am intending to get rid of aging Intel 1U server I have which is running as a ESXI box with hackintosh OS X server and Windows 2008 server, I am also intending to get rid of my 5 year old quad C2D desktop. I plan to replace with a 12core Mac Pro 2.8Ghz with a GTX 770. On this I will run ESXi, with OS X server, Windows 2008 server, and Windows 7 desktop. I want to use the Windows 7 with GPU/PCIe passthrough, and USB VMDirectPath. As i want to play the occasional game. Mostly racing games, like iRacing etc with the use of a Steering wheel with Shifter, so will need 2 USB for that. Has anyone done something similar? What is the performance like? Anyone see an issue with this setup? I am not a full on gamer, I do like the occasional racing game.
