Core 2 duo's at 1.8ghz on PC have been phased out and are old news . But, no, the MAC wont perform better with the same CPU. you can compare the exact same 1.8 on pc as mac. What you are really comparing, between mac and PC, is MAC OS and Windows. Its hard to compare performance of the OS's, as different programs will perform differently depending on how well they were designed to run with the operating system. Install win7 on the mac and compare it for yourself. Also, you do know protools is made for win7 also....right? PC's also have excellent sound card hardware made for them....not that im trying to put you off the mac or anything....
thanks for all the help guys, i guess ill find out which will perform better for me. The mac is only $400 so even if im not entirely happy with its performance, im still getting the experience.. best way to learn. Its not like im gonna ditch this comp, ill have both
ill let you know how i think the 2.8ghz Pentium D competes with the 1.8ghz core2duo
the whole reason i want to give it a try is because ive had troubles with drivers etc for my recording interface, and i know most producers use macs.
