I am in the decision making for my new mac pro and I am trying to decide which one is right for me and my needs. These last few weeks I have been reading and trying to decide which Mac Pro I should buy. I have come so far that I am going to buy a Octa 2.26 or a Quad 2.93. But we are talking about allot of money so what I want to get out of this purchase is a reliable model that will last me 4-5 years from now. Today I am sitting on a PowerMac Dual G5 2.5 and it is just too slow for me. I am the kind of person that gets irritated if something takes too long once I have pushed the button! I am a hobby photographer and programmer. I work in the following programs: PS Flash Illustrator Lightroom Xcode (Low level programing C) I have been thinking allot about the future and how I think the software will be developed and from that perspective been trying to decide if I need 8 cores or if I will be fine with 4 cores. This last few weeks I have been thinking about how I use my PowerMac and how many programs I am running at any given time. This just to try and sort out what kind of user I am. When I am working hard the most programs that I use at the same time are PS, Flash,Illustrator, Lightroom, Itunes, Firefox, Thunderbird and VLC. Here is a small list I have compiled of pros and cones: 2,26 Pros: 8 Cores. Can take up to 32Gb RAM. Cons: Only 2,26 Ghz. Is about 100 more expensive. Is slower in singlethreading. Can only handle 1067Mhz RAM. 2,93 Pros: Speed at 2.93Ghz. Is about 100 cheaper. Gives more speed under the mouse. Might be able to use 1333Mhz RAM when I upgrade from 6Gb. Cons: Can only take 16Gb RAM. Is slower in multithreading. For the kind of work I do I have reached the conclusion(Now as I am writing this) that I will do fantastic with the Quad 2.93 and that I most surly won´t be needing more then 16Gb of RAM in the next 4-5 years. The programs that I use aren´t good at multithreading today so to get the most speed right now is to get the 2.93, but programs will change over time. However I have come to the conclusion that I am not a power user in that remark that I work with 3D or other sorts of video or rendering programs that always will be needing maximum amount of cores. And I will most likely just work with a few programs at a time. There for I am planing on buying the Quad 2.93. The exact system that I am planing right now is: # One 2,93 GHz Quad-Core Intel Xeon # 6GB (3x2GB) # 640GB 7200-rpm Serial ATA 3Gb/s # ATI Radeon HD 4870 512MB # One 18x SuperDrive # Apple Mighty Mouse # Apple Wireless Keyboard # Apple Mini DisplayPort to DVI Adapter Do you agree with me? Can you come up with any reasons why I should go for the Octa 2,26? I will order my new Mac Pro on Monday so I am all ears till then!
