I am thinking of buying the 20" iMac (base model) and adding 4gb of ram to it. I don't really need a better graphics card, as I own a PS3 and a Wii both having better games than mac or windows. I mainly use my computer for listening to music, browsing the internet and doing some kind of school work. The LCD I have right now is 3 years old and a TN pannel, so the screen quality should not really bother me as I am satisfied with my current screen. Oh and before someone suggests me to go for the 24" model, I neither have enough money (it 1600 euros over here in the EU) nor space. So why do you think should I buy the more powerfull 20" iMac?
