Possible custom HD 7970 on (or near) release?

[Grooveriding]

Here's a couple of reviews of the XFX custom 7970.

http://www.kitguru.net/components/g...0-double-dissipation-graphics-card-review/21/ : This one pushes the core to 1200MHz which they say is the highest 100% artifact free they could achieve.

http://benchmarkreviews.com/index.php?option=com_content&task=view&id=858&Itemid=72 : This is another review, but here the OC done is in Overdrive, up to the application's limit (1125, 1575).

I'm not convinced, if it starts getting artifacts after 1200MHz, I must say. How are Sapphire going to get 1335MHz out of the thing then? :|

Doesn't sound as if he gave the card any more volts, just upped it with the Sapphire Trixx program. I'm waiting to see results of people using the updated version of MSI Afterburner with 7970 voltage control/overclocking

Any high clocks are going to need voltage control. Looking forward to seeing some users results here and elsewhere to see where the chips fall with overclocking these cards.
