Hi, Lately I've been using Photoshop CS6 with a pen tablet and oftentimes the program will halt, the fan will go all the way up, and I won't be able to anything. I have an early '11 MBP and I've been considering upgrades, so what do you think will benefit Photoshop more? I've been looking at the prices and I really don't think I can do both. So either more RAM (I got 4gb) or an SSD (replacing the original 320gb drive). Thank you.
