I just bought a 24" iMac. it will be delivered sometime this week. I was just wondering whats the max number of external monitors it can support? Is it one or two? if its one then i will go with one 24 or 27/28 inch. if its two then i will go with two 20/22 inch ones. Also whats the max amount of ram supported on this? does the intel platform support 4gb of ram or is the max amount 3gb? if i run vista 64 bit will it be able to see 4gb?
