I have a 13" MacBook Core 2 Duo. 2ghz, running 1 gb (2 x 512mb) of RAM. I am going to upgrade to 2gb (2 x 1gb) of RAM to boost performance, but I'm wondering if there are some other tricks to boost performance? I usually am running photoshop, mail, browser, word, and maybe a couple other things at a time. Any ideas!?!?!
