I sold my Mac Pro 3,1 in 2010 and decided to go the hackintosh route. Now in my experience the hackintosh is great if you are going to be using the computer for general computing, but for more serious work there was always an issue here and there. My first build was rock solid but there was always at least one issue with each motherboard that I changed to or upgraded. I was using my machine for doing visual fx work, music production and some light gaming. Firewire latency problems for audio interfaces and buffer settings, blackmagic capture card issues, power management issues and performance issues. I could get everything to almost work but never 100%. Each change broke something else, and not even the system updates cause even on a real mac you don't just update the system for a work computer without research and compatibility issues. I sold my hack and got a 5,1 model with a W3690 and ohh man it's so smooth and everything works. The amount of time and money I spent getting everything to (almost) work and hardware upgrades was more than I would of spent if I had just gotten a real MacPro back then. Just wanted to share my experience as a power user going from a real mac to hack and then back. I will say that the hack is really great but for serious work with a lot of third party hardware and specific needs it's not recommended, there is just too much crap to get and it's never 100%. Works great for a light user or even a heaver user but for the pro, it just doesn't cut it.
