Hi all, I have decided to have a Sapphire Vapor-X (dual fan) 7970 and was thinking of getting a GHZ edition because of the better overclock capabilities compared to other stock cards but I have heard rumors that the new ones are all voltage locked which makes me think if I will even be able to overclock it very much at all. The non-ghz edition card I am looking at is here: http://pbtech.co.nz/index.php?z=p&p=VGASAP7973&name=Sapphire-HD7970-3G-OC-Version-PCI-E-3.0-Dual-fan-V
and the Ghz-edition is here: http://pbtech.co.nz/index.php?z=p&p=VGASAP7974&name=Sapphire-VAPOR-X-HD7970-GHZ-EDITION-3G-GDDR5-PCI-E
Just to clarify I am going to overclock no matter which card I get but want to check if they are voltage locked (I really hope not), also is it worth me getting the Ghz edition anyway because I plan to try to get 1150mhz overclock so would I be able to do that on non-ghz edition? I'm pretty sure you can but just checking
Thanks
