If the Core2's ever come out, I figure the slowest part of my system will be the Hard Drive. I originally had planned to get the 74GB Raptor for my boot/applications drive, but the cost is making me think twice. The contender is a WD 160GB SATAII drive, both have the 16MB cache. The use of my computer revolves around having Illustrator, Photoshop, After Effects and sometimes Flash open at the same time, which these apps hit the paging file pretty hard. I've read most of the user reviews that say boot time is is cut down and application load times are cut down as well, But the performance I'm mostly concerned about is switching between apps while under heavy use. Would like to hear your opinions. Thanks.
