My 17" MBP from 2009 has had power issues and runs mad slow. I've taken it to a bunch of mac repair places and no-one seems to be able to fix it. Alas. Time for a new machine. I'm looking at refurbished 15" MBPs and have a few questions: 1 - Should I pay for the extra RAM? My computer right now has 8 gigs of RAM and that has always been enough. I use it for video editing and making music. The only time I wish I had more is when I use Compressor and can't really do anything else with the machine, but generally, 8 has been enough. My thinking is that I will go with 8, and if I need more, buying 3rd party RAM will be about as much as getting it from the get-go 2 - Which video card do I want? I'm not a gamer if that makes a difference. I dont quite get the difference between the machines with just an NVIDIA card, ones with an Intel pro card, or ones with both. I went to the Apple store the other day, and the salesman did a poor job of explaining it to me. 3 - What speed to I want for a processor? I know that sounds really basic, and I know there are websites that describe the speeds. But I don't quite understand what those numbers mean practically. Realistically, the only intensive stuff I use it for would be film editing or music software. I imagine almost any intel i7 will be OK. But is that naive? Here is the link to the refurbished options if anyone wants to give me specific advice: http://store.apple.com/us/browse/home/specialdeals/mac/macbook_pro/15 Thanks in advance!
