I am the (proud?) recipient of a Dell XPS 710 gaming PC from a very kind, upgrade-happy family member. I am also the very proud owner of a late-December 27-inch i7 iMac, on which I have been happily enjoying Bootcamp'ed Lord of the Rings Online, Fallen Earth and Crysis. Has anyone been successful in running a desktop PC through their iMac? I can upgrade the video card in the PC and, with the 8GB of ram he has installed and the metric a$$-ton of games, enjoy the beast for a while. It would be seriously awesome to be able to switch back and forth between the two, I am just checking with you guys before I commit to the upgrades and adapters.
