just a quick question, 7970 ghz from sapphire or 7970 royal ace from club3d?
I lean towars the club3d because it fit's better with the asus crosshair v formula z and apparently it overclocks like crazy...
The gHz edition is faster.
the club3d is the ghz edition, it's just named differently...
Go for the CLUB3D, a quick quote from the site "Extreme Gamers require Extreme performance. The PokerSeries royalAce GPU's has been cherry-picked for extreme performance."

Jack
