I use my pc heavily. I have 39 web pages alone opened up right now and my computer still runs very fast. It has a dual core processor and 2 GB of memory. I am running XP (it came with Vista) because XP takes less memory to operate. The laptop is a little over two years old and runs great. No problems. Other computers I have bought in the past even if I bought the higher priced ones they would eventually in a few years time start to really slow down and I would not even open up this many pages but this one does a LOT better. This one cost me over $1400 though. I am sure the new ones out now for around $500 probably run just as good. That $300 one does not have the dual core processor.
