I have a macbook pro 2.4ghz intel core 2 duo with 4gb ram. I've been having problems with hangups, and just barely it froze on me. I had firefox running with multiple tabs, photoshop cs3, msn messenger, transmission, itunes playing, quiksilver, and speed download but it wasn't doing anything, and gmail notifier. I also have shadowkiller if that makes a difference. I have a wacom cintiq which is the tablet that connects through dvi and usb and has it's own screen. This is basically a normal day for me, running all of that. My photoshop documents are 5000x3000 at 300dpi. on average. Now I guess my question is, am I asking too much from my mac? Do I need to calm down on what I have open, or is this something that my computer should be able to do. I'm considering reformatting but I don't know if that would make a difference. I have time machine running so that's nice if I do end up doing it, but as far as macs go i'm new. any advice is appreciated.
