I plan to upgrade some of the computers in the house. I plan to get an iMac (for word processing, itunes, Aperture and iMovie). I also need to upgrade my windows desktop (which is only used for gaming). I think I have two options: 1) Get a top of the line iMac 27inch with the 680mx, bootcamp with Windows and ditch my old windows desktop. Use the iMac for business and gaming. 2) Get a lesser iMac (potentially a refurb from last year) and go a head and build a new windows desktop. I largely play flight simulators (FSX) and military simulators/shooters (Armed Assault series). I would think Option 2 is probably a little bit more expensive (but not much so especially if I get a refurb iMac since I can build a desktop for about $1200). Option 2 would be more flexible and probably more powerful as I would build it myself. Does anyone have experience with the types of games I play on the new iMacs with the 680mx. Any two-cents on my options is appreciated.
