After complaining that my 2008 Macbook pro was gonna die soon, my company gave me another hand-me-down. I have a 2.8Ghz Core 2 Duo. I immediately upgraded to 8GB ram, but it still seems very sluggish. It will often freeze for a moment when running basic applications, as well as not keep up when I'm typing at times. Anything I can do to help with this, or even w/ 8GB RAM, is this just as good at this computer will run on Mountain lion?
