I have an Asus HD6870 DC so its a little overclocked. Now I know nothing about overclocking. I know that I could oc it with smartdoctor...software that comes with the card. First, should I try to oc it? Is it worth it. I will be playing WoW mostly and in the near future StarcraftII. I dont know if I it will be worth oc. If It is...How do I do it? should I use the software? Please know that I dont know much about this stuff...I am trying to learn. Thanks.
