I am a Civil Engineer who does a lot of design work. I originally built this computer with a Corsair 550W 80+ Gold PSU and a Radeon 270X GPU. Both of which performed well at first until I loaded the GPU drivers. Which totally screwed up my system, after lots of trial and error I figured that out and rebuilt my machine. I got a killer deal on my Quadro 4000. Getting that part for 125$ on Ebay was awesome to say the least this new set up is unbelievable I haven't overclocked it..yet. Soon I hope to add 16 more Gb of Ram and get a few better monitors but for now it is doing a great job. I have 3 hard drives running Windows 8, Windows 7, and Ubuntu separately. Soon I plan to add another for a hackintosh set up (Just for fun) all together I think I spent 1100$ on the entire build, I would call that a miracle I anticitpated spending at least 2000$ for this much. If I could change anything I guess I would have gone with an x99 with a 6 core i7 but hey, I can draft plans and play games all day without any problems at all. So tell me fellas, what do you think?
