Hey guys I have a Gigabyte windforce 6870 with an OCZ zt series 650w powersupply. I was wondering if I could overclock my gpu and how? My friend suggested me to use MSI afterburner (no idea what it is).

How much would overclocking increase my performance in games and is it worth it?

My gpu clock is 915MHZ and 1050MHZ.

Help would be appreciated! :D

I would go to youtube and watch some videos on how to OC your card. Yes MSI Afterburner is a good tool to do that with. But you need some idea on how to go about changing the values on your card.

So I am going to link you to some stuff to help you in your quest to OC your card And I want to wish you good luck on your journey. The first two links are MSI Afterburner and its user manual.

I believe the Gigabyte Windforce already comes factory overclocked , the standard clock is 900mhz and as with any overclock you can only take it so far and then you have to start adding voltage to keep the card stable. I think it's a good idea to overclock but when you have to start adding voltage it then becomes complicated and you really need some experience to help you make the overclock stable. I think you can take it up to 950 before adding voltage and in the end you will probably see about 5 to 10 fps increase. The thing about adding voltage to a gpu or cpu you take the chance of shortening the life of the processor , so is it worth it? Probably not.

Not recommended.

The new cards HD7000 and GTX600 series are overclockable. Most previous cards run within 5% of their maximum so be warned.
