Need some advice from experts. Some backround info: 1) in Texas so I don't have to pay tax if I buy from MacMall or Amazon 2) only surf internet, you tube and very light gaming. No photo editing or programming involved, so extremely light computer user. I'm not a heavy gamer by any stretch but currently dabble in some Team Fortress 2. 3) I need a desktop but I don't want a Mac Mini nor want a PC since I want to stay in Mac OS. So....which better suits my purposes, I may get back into some moderate gaming in the future: 1) new 2011 base 21.5 (i5, AMD 6750M) from Amazon ~ $ 1,125 (would the graphics/processor be adequate for light gaming and possible moderate gaming in future??) 2) refurb 2011 21.5 from Apple (i5, AMD 6770M) ~ $1,373 3) "new" closeout 2010 27 (i3 3.2 ghz, ATI 5670) from macmall ~ $1,350 4) "new" closeout 2010 27 (i5 2.8ghz, ATI 5750) from macmall ~ $1,435 Spent some time with the 21 vs 27 in the Apple store and think the 21 may be too small but 27 too big. If I go with the 21 I will buy an external monitor (probably the LG 23" IPS for ~ $250, thus closing in on the cost of a base 27" from macmall). All are within my budget but obviously the less I spend the better !! Thanks in advance or if you have any other suggestions.
