I also want to point out that cleaning your laptop's cooling system once in a while will have a huge positive impact on performance.

After two years, the heat sink can accumulate a pad of dust a half-centimeter thick. My old laptop would overheat and force-shutdown.

If you know what you're doing, you can disassemble the laptop yourself, or just take it to a professional who will do it for $40. After doing this, my performance doubled and the overheating stopped.
