I'm thinking about getting a 13 in MBP, I'll be using Photoshop, Maya, etc. My only problem is I'm not familiar with the intel hd graphics 3000. How does it compare to the 320m? Also would upgrading to either the 8gb ram or 128 gb SSD be worth it? I'm already pushing my budget at $1200 so hopefully getting at stock settings would be good enough. Thanks for any help you can give me.
