7970 overclock likelihood?

Depends. If you can get to 1125/1575 without touching voltages, or increasing voltage a small bit then it probably will.

I'm about to order the rest of the parts for my new system and i've read that the 7970 overclocked to 1.2ghz is better then the 680 overclocked.

Which would make it the perfect choice.
 
Well its a matter of opinion which one is better when overclocked, I suggest you read up some reviews showing performance when overclocked. Most non-reference cooled 7970's will hit 1200MHz now as long as you arent afraid to add a bit of voltage.

Be careful of the Asus card, some seem to be voltage locked which restricts overclocking. What resolution is your monitor?
 
1ghz is pretty much garanteed on stock volts (hence the Ghz editions). 1.1ghz may require a bit of voltage tweaking. 1.2ghz will require a bit of luck.

1920x1080

MSI Lightning Radeon HD 7970 OC 3072MB and Asus 7970 HD 1010MHz 3GB Direct CU II

Are the 2 i'm looking at.
 
My reference 7970 will bench and game 1.2ghz at 1.25v with the GE bios, but tbh the most you need to run for most games on their highest settings is about 1150/1600 at 1920x1080

Can i change the voltage ok with afterburner?

And would it game at 1.2 without the GE bios?

Depends. AMD's last two driver releases have increased performance in a lot of games. Performance in BF3 is up about 12% (maybe a little more) since the launch day driver was released.

It's gone so close that he 7970 and 680 both have the upper hand in different games. It's really down to preference, but since the 7970 is ~£70 cheaper than a 680 than that's the way to go IMO.

Pretty much what i've been thinking.

And i've had 2 main Nvidia cards for the last 4+ years, 280 GTX and 2x 1gb 460's. So i think its time for a brand change.

MSI lightning here i come!
