So you thought the 1.26 GHz core - 6.30 GHz memory feat was quite something, considering that Sapphire already has a card in the works that does 1.33 GHz core 5.73 GHz memory out of the box? Wait till you see the numbers an overclocker for the MyDrivers community achieved. With the right voltage assistance, coupled with the right kind of cooling (liquid nitrogen), the overclocker achieved a Radeon HD 7970 overclocked speed as high as 1700 MHz core, and 2000 MHz (actual) or 8.00 GHz effective GDDR5 memory speed, churning out memory bandwidth of exactly 384 GB/s. The best part is that this wasn't a hit-and-run feat, the setup was able to run 3DMark 11 and 3DMark Vantage. The scores are pictured below. Details of the volt-mod can be found at the source.

I was gonna say...it's been what...a week? 1700 MHz already?

Those 3DMark scores are rediculous.

BooHoo. One bad experience doesn't make the entire company suck.

It's a chance. You have every bit a chance of having a bad experience with an nVidia product as with an AMD product. You just got unlucky :p

Anyways, now I see that 1.3GHz on the water cooled Sapphire card is actually very less.

I'm expecting those cards to overclock to 1.5GHz core and 7Ghz(lets hope) memory!!!

WHEN ARE THEY LAUNCHING ALREADY??

Full court press on webz for the 7970...yet nada on the card most people are likely interested in (HD 7950). January 9th may be launch day for both, but I suspect that you'll have more chance of catching Lindsay Lohan sober than buying a 7950.

When I read this I sharted, my wife creamed her pants, and my dog pissed on the floor, unable to contain our excitement.

Seriously, these cards are just begging for water cooling and 1.5GHZ.

It's not useless - there will be people running CrossFire setup on boards with only 16 lanes (= LGA1155 platform). Doubled data rate makes 8x/8x PCI-e 3.0 function as fast as 16x/16x PCI-e 2.0. With ome OC people are going to run into bandwidth cap.
