7970 VS 7970GHz

Ok so I'm wondering if the 7970GHz edition is really worth the extra amount, because if it is just factory overclocked I could do that myself.

No just over clock your 7970 regular to 1ghz and then its the same

K that what I was think save me 60 bucks when I buy it.

The Ghz edition also has a boost clock thing that I don't honestly know much about. Probably not enough difference to warrant 60 bucks, but they are not strictly the same.
