I currently have a 15" MBP mid 2009. Running OSX 10.8.5 8GB of RAM I also have the Apple 24" Display I do a good amount of photoshop and am running CS6. I've noticed since upgrading to 10.8.5 and CS6 the laptop is slowing down. Quite a lot of beach balls. Option 1. Will upgrading to Mavericks or to a SSD speed things up? Option 2. 13 rMBP with 16gb RAM 256SSD or 15 rMBP with 16gb RAM 256SSD Will the 13" be good enough CPU wise?
