I am looking into getting a G5. I would love a G5 PB, but they are to much of a rumor at this point for me to consider one. This leaves me with the PM and iMac. Let me start out by saying that I do not like the looks of the iMac. (well its not bad, but I prefer the look of the PM/studio display better) The 17'' iMac is at a good price, but its not what I really want. That said, there is the low end PM and the DP 1.8ghz PM (refurb) that I am considering. (and a cinema display.) I hear that the 1.8 SP has a different processor than the 1.8 DP. The SP is the same as the iMac has from what I understand. Is this correct? and can anyone point out any other differences between the SP 1.8 ghz and the DP 1.8ghz? Also, how does performance compare between the two? If it is infact the same processor in the PM as in the iMac, is there any advantage to getting the PM over the iMac? It will cost about twice as much, granted I would get a 20'' cinema display vs. a 17'', but I dont really need the extra space. So bottom line I guess, what do you think? 1.8 iMac G5, 1.8 SP PM + cinema, or 1.8 DP PM + cinema. Is the aditional cost worth the performance increase in each case? I will just be doing basic stuff.
