I've read different things, so I just wanna get it straight. Is the extra ".2 GHz" enough of a reason to pay $200 to swap out old model for new? I do a lot of graphic editing and music recording. Will there be a noticeable difference? Or at least enough of a difference to justify paying the $$$? I dont care about the HDD because that can easily be swapped anyway. I bought my laptop exactly one week ago, so I am still in the 14 day period. I wanna know what you guys think before I decide. Thanks!
