Hello macrumorsfolks! My 4 years old 15" macbook pro 2.16ghz got his Ati gpu broke, so to repair it i've to replace the logic board. (not available at ifixit and really expensive at apple support) As replacement, for now, i'm working (graphic and web stuff) with my girlfriend 13" macbook pro 2.2Ghz, i'm used to have a lot of softwares and browser pages opened at the same time each in his spaces desktop. I don't want to stress too much this machine as i got problems with my old 15" macbook pro because i've stressed it a lot in 4 years: travels, 16-20h per day powered up, 3d modelling and rendering, music composing and a lot of other intensive tasks. So i'm thinking to go for a Mac Pro, i went to an Apple retailer to see also the iMac 27 but after touching the rear case of it, and noting the heat at 0 cpu use i decided to go for the apple tower model. Choosing this model i had also to think about quad, exa, eight etc... I've tought about my use that will be mainly 2D graphics and music production, rarely something in 3D and video compositing/post-prodution. I've tought also that with music production i use a lot of AU plugins, that are almost all single-thread useable. Unless if i'm wrong in calculations what is best for me is an "higher CPU clock" solution than a "more cores with slower clock CPU" solution. In my opinion, always unless if i'm wrong, the best would be the 6-core 3,33Ghz Quad core machine. At almost the same price i could get the Eight cores model, but with 2.4Ghz slower cpu clock. I could afford one of these two machines only after a work that i'm doing at the moment, this means that now i can only afford the Quad 3.2Ghz model. Now intel released the new Xeons E7 cpus, that will have, in their top gamma, a max clock of 2.4Ghz I wonder if Apple updates the MP (end cycle on buyer's guide) will use these new cpu with more cores but slower cpu. Assuming that now i can also wait before buy, i'm not really in a hurry, What's your advices? -Wait to see the next MP update with the risk of a more-cores but slower clock machines offers. -Go and buy the Nehalem Quad 3.2Ghz -Wait 1-2 month (with the risk of an imminent update) to save money and go for the Westemere Exa 3.33Ghz. -Don't care about single threads softwares/plugins and buy now the Eight 2.4Ghz Thank you for your time!
