I'm a film student and edit a lot of high definition films on my personal laptop. Right now, I'm running on a Core 2 Duo 2.2 GHz with 4 gigs of ram, 7200 rpm drive, and a Geforce 8600M GT 256 MB (Dell laptop). It bogs when I start to do anything relatively complicated. That said, I ordered a 15" i7 2.66 GHz with 8 gigs of ram, 7200 rpm hard drive, and of course the 330M 512 MB. For something like video editing, will this new configuration help a lot? Anyone with experience with really heavy tasks such as editing can fill me on on the difference I should expect? Thanks!
