I am a total newb and finally have the $$ to buy an iMac. I want to be as frugal as possible while getting the best I can afford. It will mainly be used for heavy photo editing. I was going to go with the aluminum 20" but after reading this forum I understand the 20" to have serious problems and that the 24" was superior. But then I read that the 24" isn't all that great either. So I'm wondering, is the aluminum 24" 2.4 display which is now on clearance any different (better/worse) than the current 24" display? And if I load the 2.4 24" up with 4gb ram do you think it will meet my needs? I am *not* a gamer. Just photo editing mainly. And I also plan to run Windows apps on it as well. Thanks in advance for the help. I've been scanning these forums for days now and can't seem to find a specific answer to my question.
