Part-time lurker, first-time poster. Many thanks in advance for your advice. FACTS - I am planning to return the iMac fold after a five year hiatus in the world of Windows PCs. - I am not planning to purchase a new iMac each "refresh" (future-proofing is therefore important to me). - I am a "casual-hardcore" gamer (mostly Blizzard titles; Starcraft and WoW). - Once it is released, I intend to spend a fair amount of time dispatching hellish minions in Diablo 3. - When gaming, I value excellent graphics and frame rates (I don't minding waiting a few extra seconds on loading screens). - When gaming, I like to play in native resolution. - In general, I do not use programmes like Final Cut Pro, After Effects or Photoshop. QUESTION - What iMac spec should I buy for Diablo 3 gaming? - More specifically: * what upgrades on the basic model should I get (if any) and in what order of priority? * 21.5" or 27"? * Is it worth waiting 4-5 months in the hope that the next iMac incorporates AMD's New Radeon HD 6990M? CAVEAT - I am aware that iMacs are not the best gaming rig (you therefore do not need to tell me that).
