That won't fit in that socket; I'm afraid. Thermal dissipation is also important; it's best to find out what the fastest CPU your notebook was available with as an option and to aim for that.
This. If you want to simply upgrade the laptop, you can try to put a better processor in, try (and probably fail) to get a better cooling system, and then overclock your stuff. Might also consider upgrading the RAM if it's not at least 3GB. Or you can get another
computer and use them both, one for lightweight stuff, and one for more intensive stuff. I generally have two computers running; my laptop handles the heavy stuff, while my old 2000 Aptiva that I've fixed up is used for lighter stuff. That's the best recommendation I can make if you want to put it to good use, which I'd assume is what you're aiming for, despite saying you didn't want another computer.
