I just noticed Vivi from South Africa put up a monster single card 3DMARK11 single card score (2nd fastest in the world) using GIGABYTE Z77X-UP7 and the GIGABYTE ODIN PSU.
Here is what Vivi had to say about the gear he benched with:
This board is awesome. and this Oding PSU doing well! haha. 2000mhz run passed too, but screenshot was invalid. This will have to do. R.I.P to this card :P. -130 on the card and 1.75v Thanks to sniperOz for the pots!
Well done mate!
