OT a bit... if you are going to use your notebook for trading, i.e. you will have the computer on all day, be sure to install a harddisk temperature monitor. (free)

Also get yourself a good notebook fan. Get one with ball bearing fans. Don't buy the cheapies. The cheapies will only last you a couple of months if you have it on all day.
