I've been trying to decide for a couple of weeks now on what to order. I've always had iMacs in the past but have grown tired of the mobile graphic cards in them out dating so quickly. I do quite a bit of gaming in osx with d3, wow and guild wars 2. I had ordered a 6core Mac Pro a couple of weeks ago with dual 700s but cancelled it after reading some initial reviews stating it's really only going to reach it's potential as a workstation. I thought that maybe an iMac wod be better suited as a general use/gaming PC. I'm curious to see how well the iMac with the 780m runs games at full native resolution. I'm really torn on what to do here and seem to waffle back and forth day to day. As I've seen there are quite a few others here that have a similar dilemma. Hopefully we can all come to a decision we'll be happy with.
