I need to buy a new Mac. We do a lot of editing along with Motion, LiveType, After Effects, and Photoshop. We are desperate to cut down our render times. Because we hire freelancers, we're paying them lots of money to just sit and wait for projects to render. I have $3000 (not including taxes or Apple Care) to spend on a MacPro. Right now, we're thinking of the MacPro 2.66 ghz, 2 gb ram, and a 500 gb hard drive. That would take it to $3000. Any suggestions as to changing these specs? Another question..how much more effective is the new MacPro than the older G5 model. I could cut my spending in half by buying a nicely equipped used G5. Thanks.
