Ok, so I have been using my Macbook for two years now and I love it! But I am doing a lot of projects related to music and it is just having a hard time keeping up. I will be using it for DJ-ing only so I need to get another Mac. What is the fastest Mac I can get for the buck? I am capable of upgrading ram and hard drives on my own, and I know where to get them dirt cheap, so that isn't a problem. I was leaning towards the 24inch iMac with highest processor options. I'm assuming this is the fastest you can get. Although the programs I'm using are huge proc hogs, but I want to be able to run a few at a time and still have some overhead. This will be used as my personal computer and my Modular Audio Machine as well. What do you suggest? Is there much of a difference in speed from the highest end 24 inch white iMac and the highest end 24 inch Aluminum one? Besides the 500.00 difference of course. EDIT - I was looking around the store a bit more and saw the prices for the Mac Pros aren't that bad. I always thought that even Refurbished these guys are no less than three grand. Here is the one I'm interested in - Refurbished mac pro Quad 2.66GHz Intel Xeon 1,999.99 Two 2.66GHz Dual-Core Intel Xeon processors 1GB (2 x 512MB) memory (667MHz DDR2 fully-buffered DIMM ECC) 250GB Serial ATA 3Gb/s 7200 rpm hard drive 16x SuperDrive (DVD+R DL/DVD±RW/CD-RW) I'm assuming that would be a world faster than this - Refurbished iMac 24-inch 2.8GHz Intel Core 2 Extreme - 1,599.99 24-inch glossy widescreen display 2GB memory 500GB hard drive 8x SuperDrive (DVD±R DL/DVD±RW/CD-RW) ATI Radeon HD 2600 PRO with 256MB memory Built-in iSight Camera NVIDIA GeForce 7300 GT graphics with 256MB memory The price difference isn't all that bad when you figure the upgradability and (i dunno by how much) speed difference. How much faster would it be compared to the iMac (with the specs as they are right now - of course I'll be upgrading a little bit). Would the difference in performance be worth the cost of the difference between the two? I already have all the stuff (mouse, keyboard, display, yadda yadda). Thanks for the help here.
