Hey guys. So I have had my MBP (refurb, early 2011) for a few months now. I love it, no doubt. I am wondering, though, if I could get more power from it. I have a 2GHz Intel i7 as my processor, and an AMD Radeon HD 6490M with 256 MB. The laptop came with 4 GB of RAM, which is adequate. I am moving towards some FCP/FCPx editing though and I am wondering if it is worth it to upgrade to either 6 or 8 GB of RAM. Any advice is much appreciated.
