Wouldn't bother with game booster, your speed problem is probably related to only having 1 gig of ram, it's very cheap to add extra ram nowday's, an extra 2 gig would do wonder's if your system will take it ? if not you should at least be able to add an extra 1 gig, and have a look at what you have running at startup to see if there is anything not needed as everything that is running is consuming memory.
