hi guys i tell you what it is i currently have: 2008 mac pro 8 core, 6gb, 2,320 gb & the default ati graphics supplied and nvidia 8800 with a 30" dell monitor plus a unbody macbook. my question is would selling this for the new 27" i7 imac and the white macbook be advised by anyone, is the i7 much better than the 8 cores in the mac pro seeing as little software uses them all? another factor is i live alone in a flat and with travel to work etc i need to save money the imac is complete all in one plugged item where as with the mac pro i have it and all the harddrives running, the monitor and the speakers thats 3 units drawing power surely there must be a difference in the power drawn. i can easily get a 2tb harddrive in the imac so im not losing space, the ram i have a spare 2gb so there is the imac at 6gb ddr3 compared to the 6gb ddr2 in the pro. i would be interested in substituting the macbook for maybe the 15" pro to supplement it. what is your thoughts on this and would you do it?
