I'm thinking about buying the new iMac 21,5 cause I can't afford the 27. What do I need it for? I like photography so for photo editing (photoshop, lightroom). Some dslr movie editing (very rare). Web browsing, movies, mp3 music and normal every day stuff. Games - not very often, I like old games - quake3, coutner-strike, starcraft but it would be fine if it could run new games like Crysis etc. Would iMac suit my needs? I'm thinking about buying the new cheaper one (with 640 graphics) and adding to it extra 8gb of RAM. What do you think? Is it a good choice?
