This post is 2 part. 1. While I can luckily (in this economy) afford any Mac config, I am leaning towards the 21.5 base, and upgrading memory myself. My rationality is I only use it for work (citrix + office) and light gaming. If I went 27 I'd be too tempted to max it out, ssd, etc... And I think it might be better to wait till ivy in 2012. Anyone else decide to go base on this rationality too? 2. If I went 21.5, I'd like multiple monitors like my current office and home setup. If I used 2 21" in a tri setup ( tb>dvi, + USB) Would it run decently with that processor + gfc? Only used for real estate, and explorer windows + citrix. Also, will it automatically shut off the other two( for performance) if I get into a game, sc2 (fullscreen),etc... Or will it be a complicated process each time to do so? Sorry for the long post.
