new macbook, laggy performance

[pigglywiskers]

I have a 2GHz unibody macbook which I got about 3 weeks ago. I installed 4gigs of ram myself and a WD Scorpio 320gig 7200rpm harddrive. I notice things like typing and animations within OSX seem to be a bit laggy. Whenever I pull down with all four fingers on the trackpad and show all the programs, the animation isn't smooth, but "jagged", like moving at a slow frame rate. Same thing when I minimize/maximize windows, and switching between tabs in Safari also sometimes takes a while (sometimes bringing up the spinning beach ball). Same thing with typing in web addresses, sometimes taking a second before registering any of the key presses.

The 2 year-old plastic iMac's at school seem to run better than my brand new Macbook. Does anyone know if there might be a problem? Am I overreacting? Would reformatting fix the problem? Any help would be appreciated. Thanks.

I would try reformatting it. I installed 4 gig on mine w/o any HDD upgrade ... everything is working fine. You should definitely not see any laggy performance for simple maximizing and minimizing windows

Do you watch porn on it? If so then porn can slow down your mac immensely.

It could be a deeper problem than this but check to make sure your RAM is in well and do a memtest. Do you use iStat Pro? If so, you might check to see what is going on when things slow down. It could be a problem with an app you are using. I tend to get that sort of problem with Safari or Firefox if they've been running a while.

I don't think porn would be the issue. Video run's pretty well (high def too), so if I were the type of person who would look at alot of porn, since none of my videos seem to slow down, the porn wouldn't be slowing down at all. You know, if I looked at porn that is.

I ran memtest 3 times with no errors, and I really only run 1 or 2 apps at a time. I don't have too much installed on here, so I think I'm just going to reformat and see if that works. Putting 103gigs worth of music back on here's gonna suck, but oh well.
