Do I buy the refurb 2009 quad core for $2150 or get an 27" iMac i5/i7 for $2k +? I keep my machines for 5-6 years. I am upgrading from a dual 2.0 G5 and need a second machine. Want to run CS4/5, Ilife suite and probably final cut express eventually. Already have two drives filling and an okay 20" monitor (want to get a much better monitor eventually) the pros / cons of the machines to IMO: MP: speed/ flexibilty/ expandabiliry/ raid potential of the MP, but will have to buck up $600 for a screen to y satisfaction iMac:the speed and fantastic real estate of the i5/ i7 are great Lack of expandability is negative.
