I'm not really an expert so any advice would be helpful. Why should or shouldn't I enable TRIM on my Samsung 470? What difference does it make? Is it needed? And also, I have money to waste so I bought 8GB RAM the other day. Will there be a difference in performance? I usually use Safari, Photoshop, Illustrator, Flash, iTunes and Skype all at the same time. The "Swap used" usually goes over 1GB sometimes more. Thanks!
