Hey guys, so after being a long time PC user I decided to jump ship and try out a Mac. I went ahead and purchased a used mid 2011 iMac 27, Core i5, 2.7ghz, 8gb ram and AMD Radeon HD 6770M 512 MB. So I do a lot of video editing and currently I am using the latest Final Cut Pro X. My camcorder uses .MTS files and since FCP does not natively support these I convert them to a Quicktime file before I import them. Now the issue Im having is Im constantly getting the "beach ball" popping up, my video in the timeline will at time go green and its just very sluggish overall. I know I don't have the best specs but I guess I was hoping for a little better performance. Will upgrading the ram to 16gb help with this? is it possible to upgrade my video card in the mid 2011's? Thanks in advance for the help
