I know the "can I use my iMac as a display" question has been asked a million times but I have a specific scenario that I'm not sure will work: When it is released, I want to use the new 2012 27" iMac as my main computer for work, and I also want to have a separate Windows PC for gaming. Desk space is limited so, ideally, I want to be able to connect the PC directly to the iMac and use it as a display whenever I want. Before you recommend using Bootcamp or software like Parallels or VMware, those aren't options I want to use. I've installed both on all of my previous Macs and end up with nothing but problems. When I get the new iMac, I'm not installing Windows on it and that's why I'm building the separate Windows PC box. Is what I want to do possible if I purchase the right kind of video card? Also, would I be able to use my Mac keyboard and mouse for both machines, or would I need another set just for the PC? Any advice is much appreciated!
