sped up by adding memory, A faster processor means faster processing but for tasks that have heavy processor use. Most apps don't test the processor.
The main thing slowing down the performance of my laptop is when I have multiple internet browser tabs open simultaneously. I know there are better ways to manage this. But aside from those, would it help to get a laptop with more cores, like a quad-core i7? What about a lower-lever quad-core AMD? What else helps for this - larger cache, RAM, hyperthreading, clockspeed? Thanks.
