on my mid 2009 15 inch Macbook Pro and the render speeds and video playback are horribly slow. I have maxed out the RAM (8gb) and have a 750gb SSHD installed and all my programs (inc. Final Cut) load up pretty quick. I have played around with the settings and tried editing using the proxy media but it doesn't make any difference. I'm thinking about fitting a 250gb SSD and storing my files on an external HDD instead. Do you think this will help or should I just bite the bullet and upgrade to a desktop?
