Hi. I am considering the new Macbook Pro 13 or 15 inch. I will be using the computer for some photoshop, moderate video editing, games on bootcamp, surfing the web. I currently Have a Quad Core iMac 27 inch but I need a portable laptop to bring the laptop overseas with me since I do a lot of traveling. Should I get an upgrade to 8GB ram from 4GB ram? or should I get an upgrade from the hdd to ssd? Is Apple ssd inexpensive compared to the after market ssds? because I know that the After market ram is much cheaper than the apple ram. Thanks!
