I'm starting to falter on getting 3 7970's. As much as i want them if Nvidia drops the 580's price enough i might just go with 4 instead.

MD Radeon HD 7970 3GB (925MHz GPU, 5.5GHz memory) (overclocked 1,125MHz GPU, 6.3GHz memory

Nvidia GeForce GTX 580 1.5GB (772MHz GPU, 1,544MHz stream processors, 4,080MHz memory)

16fps more on BF3
Now remove the bandwith advantage and take into account the stock vs Overclocked card.

Suddenly the performance difference and the GPU performance increase doesnt look that big. And this is against the competitors old stock.

Did you magically skip this page? I am pretty sure the graphs you are referring to are stock clocks.

Guru just posted they could only hit 1272 core on their reference 7970 at 1.3v. I'm dying to see a comparo between a 1Ghz core GTX 580 and a 1.3Ghz core 7970

First off, there's a problem with BF3 and AA on AMD cards. The performance is lower than it should be. Pretty sure AMD is aware of this and we should see a driver update soon.

Check Tom's benches with No AA, there is no comparison:

At multi display resolutions the 7970 is nearly on par with 590 at stock:

You're not reading the graphics correctly. The 7970 is ~25% faster than the GTX 580, stock vs. stock.

Got a link? I'd be interested in reading up on their experiences. I'm betting these cards will respond very well to cold.

With software voltage control. Amd is making it very hard to enable hardware voltage control.

Starting to look like 1300mhz will be the max core on air, 1400 on water and 1700+ with ln2

Hardware voltage control is a pain anyway. I haven't soldered on a trimmer since my 4870 (nor do I want to go back to that). As long as I can get over 1.3GHz (40% overclock), I will be content.

Hardware volt mods are a pain. I haven't had to mess with trimmers since the 7800GT days.

Going by 3Dguru:
Looks like 1.25-1.30volt = 1250-1300mhz core. (YMMV)

@1.3volt's and 1278mhz core,
they stay under 70 degree's celcius @70% fan speed dureing stress testing @100% load.

still.... 925mhz -> 1300mhz (~40%+ overclock)

These pretty mighty overclocks. I thought with this release the OEMs were allowed to ship overclocked and custom cooled cards from the very beginning? If that is the case then I suspect we might see cards that have considerably higher clock speeds that AMD's recommended defaults.

They benchmark some truly worthless games. Very strange....

The only thing I even felt like clicking to see was Metro 2033.

That's the first thing that I thought as well. Why are they benchmarking games that are fairly old and most people don't even play anymore?

Where is the current main benchmark game, Battlefield 3?

That and they have no idea how to use a dB meter - all they're picking up is air moving/noise because it's too close to the card.
