I just got a new MacBook Pro a month ago. It is the i5 2.4GHz 15inch. I run a lot of high memory intensive software and my Mac is hot a lot of the time. I rip like 6 DVD's a week. My mac is usually at like 78 while ripping and hot when it switches over to the Nvidia video card and running a few apps. I am just wondering if i would have bought the i7 instead... would it have run even hotter then my i5 does? Right now, im at 46C... if i had an i7 right now, would it be hotter than 46C right now? I bought the i5 and plan on upgrading to 8gigs of ram soon. I did this b/c i wanted to be able to actually use it on my lap w/o it being super hott. will the i7 run at the same temp as mine? should i have got the i7 and not the i5. Is it worth going from 4 to 8 gigs of ram? I just feel like my i5 with 8gigs of ram will basically be even to a stock i7. and if so... paying $400 for the ram upgrade would have been the same $ as buying the i7 and leaving the ram alone. Is 2.4GHz i5 (8gig ram) = i7 with 4gigs ram??
