Ok, I know I already made a thread about, please help me in keeping my mac pro... but recently I sold my 15" sr mbp at a good price and bought the 17" 2.5ghz mbp! And it does feel alot faster overall and could be used as my desktop replacement/laptop.. Now I'm starting to use the mac pro less and less but still love to sit behind a desk most of the time to do alot of work/play. But ever since I found this one method out, I want to sell the mac pro. The method of extracting 9gb + files, what I do is that I have an external 1tb drive fw800 (and its very fast seagate barracuda ns model) and I hook it up to the 17" mbp and drag the folder to the seagate 1tb drive, then from there I extract the file using macpar via external hdd and it extracts the file in 7 minutes! I've tested the same folder on the mac pro with the raptor 10k and it extracted it in 5 minutes.. So now I want to sell my mac pro and is currently listed on ebay for a good price...and I keep telling myself you have a machine that does what you want it to do and does it fast still.. but everytime I look at the mac pro I'm tempted to end the list and to keep the mac pro all over again. That 8 core keeps calling out to me!! Also on the other side I keep thinking to myself sell it and pocket the money and use what you have and the new nehalem will be out and you wont care as much anymore. And another part of me saids who cares if nehalem is around the corner something better will be around when that comes out and your 8 core will still be a monster workstation!!... Man help!! I'm so stressed out!!
