I currently have the macbook 13in 2.53 model. I originally purchased it as a secondary computer to go along with my Mac Pro at home. It was intended for minor video editing and photoshop work, and has done the job pretty good. However I've recently sold my MacPro and now have been using the MBP as my primary machine, I now work in motion graphics and have been using aftereffects and photoshop non stopped with large High Rez files and this thing chugs along, really bad render times, and just laggy HD Video play. It obviously wasn't made for such things and my question is if I sell my machine for $1300 today (btw is that a good price? I spent like 1,700 with APPcare)... and purchase the MBP 15in 2.8 with dedicated 512mb graphics card REFURBISHED for basically $2,000 will I see a huge and I mean HUGE difference? I mean I will be spending an estimate of $750 in total for an upgrade, I get the 2 extra inches of HIGH REZ Screen, 2.8 processor BOOST, same ram, 250 more HD space which is whatever, and more importantly to me the 512mb dedicated Graphics card. I mean in the PC world with $750, let alone 2gs I can grab an amazing set core i7 setup and probably pull a hackintosh but realistically who wants to go thru all that I love/hate unfortunately. So yea my question is, is it worth it? $750 for the upgrade, will the graphics card even help with my aftereffects rendering? I don't know how that works or what it relies on... processor speed or ram etc.. Thanks in advance for the suggestions PLEASE post up any links rendering test that might help my decision.
