Hey guys, so I'm kind of a newbie when it comes to finding the correct computer parts to run my Macbook at it's peak for video editing. I bought a Macbook Pro 13" with 4GB of RAM and upgraded it to 8GB but when in editing with Final Cut Pro, my composition with green screen really uses a lot of my RAM. In activity monitor it shows that my free memory is about 79MB. So my question I guess is whether I should upgrade the RAM higher to two 8GB cards for a total of 16GB or if I should maybe check into getting a customized video card. I've heard they both could be potential problems so any help is appreciated. Thanks.
