Hello folks, I've decided to go for an iMac. I was previously looking at MacBooks, but I've decided to go all out. My decision concerns whether to get the top-end 21.5" (the i3 with the HD 5670) or the top-end 27" machine (the i5 with the HD 5750). I think the issue that concerns me is how well the 1440p display of the 27" iMac will deal with lower resolution graphics - will they look smeared or fuzzy? My needs are largely productivity, with some gaming on the side. Any thoughts on this matter are welcome. Cheers, DH.
