I got downloaded game booster after I think it was montycz who recommended it always found it seemed to work ok for me and the razer game booster is essentially the same but its claimed to be more enhanced and with added features ie:screencast etc and after all it
is a joint project between razer and iobit , I also notice it requires online registration. As far as optimizing your computer goes always found Tweakguides Tweaking companion to be real handy for me as I really don't know my A from my E anyway and for anybody with
win8 tweakguides has a tweaking companion coming out early Dec for windows8
