Overcloking an 7850 does give performance?

Hello

Interestied in overclocking my gpu to gain some performance maybe? equal to a 7950 or GTX 670 i dont know if i can do that
or just get CROSSFIRE?

Also what program can i use to see in-game FPS and Temps?

Thanks aigain to this beatifull forum that learned me a way of lot things 

MSI Afterburner

My cpu is core i7 3770k so thats not a prob

GPu temps on 100% load are 52C on 3dmark/heavy shaders on games

So i think that gives me a lot of headroom but how much speed should i aim?

Go for "7870 XT"(and overclock) if you want a GPU that can rival 7950. http://www.techradar.com/au/reviews/pc-mac/pc-components/graphics-cards/sapphire-radeon-hd-7870-xt-1130535/review

to start the oc what voltage should i put to memory and core clock?
also how much to aim for first and how to test it

This is the best possible guide on overclocking, I know because it helped me and I never even tried to OC anything before. And it also applies to every GPU on market. It includes what programs to use to test your OC for stability, how to get your card to its max 2% and how to set up a good fan curve to keep temps. from reaching 90C-95C. It's also really simple and teaches you what the abbrevations mean. If you still have problems you can message me on a PM or via email if you want.
