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?
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.
