Up until last year I have used custom built PC's for gaming, and done my everyday computer work on an early 2008 13" Macbook. Since then I have moved several times across several states for school and work, and I ended up parting out my gaming computer to avoid the hassle of taking it with me. At this point I am just using my old macbook (which still runs just fine). Anyway, now I finally seem to be in a position to try to upgrade my system. I would have held off for a bit longer but with Diable 3 coming out soon I would really like to get something to run it on. I was originally intending on just upgrading to a 13" Macbook pro, and had given up on PC gaming entirely. I just figured Diablo 3 would never come out, and when it finally did, well I'd just throw something together for it. I just really don't care to have a PC just for gaming (especially when I'll most likely only be playing one game). I wish I could just get the 13" Macbook pro and play it on that, but it doesn't have the graphics processing I need. I considered a 15" but they are out of my price range and a bit bulky for something I would want to carry frequently. I do like the idea of the 21.5" iMac. It's just hard to even justify a desktop with my lifestyle, but the pros are there: a big HDD to transfer most of the data off of my old laptop to clear up space, a nice big screen for Photoshop, and a centralized system I can share with my girlfriend. Sounds great, but the real question is Does a 21.5" iMac seem like a decent machine for running a game like Diablo 3? Has anyone been using an iMac to play newer games, and how do they run? Is anyone planning on running Diablo 3 on their iMac, or looking to make a purchase similar to mine to run the game?
