Hi, my first post, and sorry if this for has already been discussed but couldn't find exact numbers. I'm planning to buy an iMac, which apart from usual stuff (browsing, office, iphoto, some programming,..) will be used for gaming. I usually play only Blizzard games, so WOW, SC2 and Diablo 3 (if it will be ever released). My desk is small (also not a big fan of the huge 27"), so I plan to buy the 21.5" with the 5670 graphic card. How will the mentioned games run and at what settings ? Has someone some detailed data at native resolutions or can post a link to them ? Also a comparison between the 27" and the 21.5" would be nice, curious to know how the two compare, since even if the 27" has better graphic card it has an enormous amount of pixels to handle. Thanks.
