It would of made a noticeable difference on the netbook I had, trust me. I switched lids which required me to take practically the whole thing apart, and when I put it back together, it would heat up way too quick, and my CPU would be reaching 90-100%. Flash plug-in alone (around 20k) would alone set it off. So you can see that I'm a little sensitive to having a fast/fresh, junkware-free computer.

Now I have an i5 with 4gb at the moment. Can't complain now

I did what you guys said and reinstalled windows. Now I practically have nothing. About to put my programs back on here.

Thanks
