This is probably as entry-level a question as it gets, but I'm so far out of the PC game that I am all but clueless. I'm considering buying a new iMac, and wanted to know what kind of gaming potential it's going to offer. I know Steam for Mac exists, but I understand that a large percentage of titles aren't set up to work in it? Is Boot Camp a reasonable option for running Windows-based Steam? What kind of performance should I be expecting (looking at the two current 27inch models) and is there any particular hardware upgrade that's worth considering?
To clarify, I'm not looking to run anything too intensive or that would better suit a console - rather just things that fit best with mouse & keyboard or that aren't available elsewhere (indie titles like Gone Home, Papers Please, The Stanley Parable etc are high up my list of things to play). Yes, I know that I could get a PC capable of these for much less, but gaming is not the only thing that I am looking to buy a computer for - hopefully this spares me a 'cult of Apple' intervention
