Hey guys, just looking for a bit of advice on the 2014 line for 15" rMBP. Pardon me if some of these questions have been answered, I tried searching and came back a little fruitless. I've been thinking about purchasing my first rMBP soon since my job is starting to take off and my 2011 laptop is a bit outdated and performing poorly. One of my family members actually uses the 2014 15" rMBP at his work and he mentioned the dual GPU version tends to run pretty hot depending on what applications you're using. Is this really a problem? Unless I'm going to try to hook up multiple displays and run CPU heavy rendering simultaneously I feel like the dual GPU is probably overkill for what I need it for. Based on what I've read the new 2015 rMBPs aren't a huge performance boost outside of battery - the new touch pad is cool but I'm not really that interested. Would there be any reason to really consider waiting for the 15" (if it comes this year) over getting a 2014 15" with CPU upgrades?
