I'm a brand new mac user. just made the switch yesterday. I just bought 4 gigs of G.skill ram for my new macbook. My mac seems to be a little laggy. I know with 4 gigs of ram it should fly. I took the ram out and put back in the stock ram which is a gig but nothing changed. i thought it might have been bad memory or whatever. I open photo booth and switch effects around it seems a little glitchy at times. not smooth as i would suspect. When i pull up the dock and click on an application sometimes the icon sticks a little as it's bouncing up and down. just little stuff like that is kind of making me think somethings up. I figured everything would just run real smooth. I don't recall my freinds macbooks doing that. has anybody tried the gskil ram from newegg? and why would the macbook be glitchy?
