Gigabyte 7970 VS Gigabyte 7970 Ghz Edition

[Seratis]

I am planning on getting a new video card, and I have decided to go with the Gigabyte version of the 7970. I know that upon looking at the newegg pages for both the normal 7970 and the Ghz Edition show that the Ghz edition clearly runs faster, but I am wondering, can't I just OC the normal 7970 to match the Ghz edition with the Catalyst or Afterburner programs and save myself $40 in the process, or is there something that I am missing that makes the Ghz edition a clear step up from the normal?

just got the ghz edition

and gigabyte have blocked increasing voltage on it to further overclock it on the latest revision cards

dont know if they have also done this on the normal version as well

they arent advertising they have done it

though their support confirmed they had done it on the ghz edition

nothing i tried would unlock voltage increasing

Best is to get Normal Ed.

You can Overclock it more than Ghz.
Ghz Ed. mostly have Block Voltage control.
Which makes them hard to Overclock.

Get the Ghz edition , it is already overclocked for you. If you dont mind the hassle and want to overclock the normal edition yourself , by all means go ahead but you might encounter more problems if you intend to do it yourself.

You'll surely get a Better boost going with Ghz Ed.
But in future when you'll feel that your GPU is weak then you'll not be able to Overclock your Ghz Ed.

But if you get a Normal, you may OC that above.

maximum i can get the ghz edition to is 1025mhz

though the memory overclocks fine to 1600mhz
