Ok guys, I need some opinions here. I don't visit these forums as much as I used to so I've sorta fallen behind in my Mac knowledge. So I have an older MacBook Pro, a mid 2007 to be exact. It's starting to show signs of just being too old so I was thinking of upgrading soon. Now I know Apple released updated retina 13 and 15" MacBook pros, so it caused me to start seriously thinking about buying a new model but I'm not entirely sure which of the 15" models to look into. I like to play games but not so much on computers but it would be nice to have the option to do so. Otherwise I do all the usual stuff on a computer plus a bit of photo/video editing. So my question is, should I grab the low end 15" or the higher one? I know the low one doesn't include discreet graphics but I'm not sure if what I need it for would really matter. Plus I don't know how the higher model's discreet graphics set performs so I don't know if it's worth spending the extra money on. Plus, I keep hearing that new Intel chips are just around the corner. Should I buy now on just wait for a future model?
