So recently I bought a HD PVR to record some games and sports and video edit and starting yesterday I started using Final Cut Pro and it has crashed on me at least twice in the past hour or so. Normally I have ichat open 24/7, Chrome with at least 10 tabs open and a lot of them are youtube videos at HD, sometimes I have itunes playing something. Those are ALWAYS ON. Then I might do things in Finder and install things or whatever. And starting yesterday I added to that list of running program, Final Cut Pro X and it crashes the program once in a while. Not instantly but if I'm doing things it'll get reallll slow, the browser will have the beach ball thing going and it's really unproductive. Not to mention I have to sometimes open Adobe Photoshop on top of all those things to edit images. I have a 13" Macbook Pro (2011) with the core I5 running at 2.3 ghz with 4gb or ram. Not sure if I should upgrade the laptop to a 15" or an Imac or if upgrading to 8gb of ram will fix this problem. It doesn't seem like I'm utilizing the CPU at 100%, but "FREE" ram is usually like 9mb. Lot of inactive ram but free is next to nothing.
