Specs of the 7950 at the Turkish "Hardware News" (Donanim Haber)

Pretty incredible that Sapphire will offer 7970s at 1335 GHz core! That's about a 40% OC.

That they plan to sell them at these speeds indicates that they have a high level of confidence that they will get enough chips that (albeit with some pretty hefty cooling solutions) will hit those numbers.

Wouldn't a 6 port, 6 GB mem card likely be a 7990? rather than a 7970?

Well, that would go against historical naming. The xx90 cards have always been dual GPU cards. They are deviating a bit, by not naming this one "Eyefinity 6".

The "Flex" name was used for cards that didn't require any adapters between the card and monitor. The old one had 3 DVI. The new one has 6 mini-DP connectors, so that bit fits... if you buy 6 displays with DP ports.

Yeah exactly this 6 port single CPU version of the 7970 would be similar to the 5870 E6 2GB version that they put out (I wish I had snatched up two when I saw them on NewEgg clearance for $200 at one point when the 69xx series cards came out)

So similar to the normal version, single GPU but with double the Eyefinity ports and VRAM to handle it.

Right you are... For some reason I was assuming that the 2X Vram meant there would be 2 cores. Nevermind my feverish thoughts

You could attempt to OC it to 1.3GHz?

Nice review of the XFX OC'ed edition: @ HardwareHeaven

Wow thanks for the nice pointer, that looks good compared to both the 580 and 6970, they also had a nice review that compared 580 SLI to 7970 CF for 5760x1080:

Powercolor 7970 Crossfire @ Hardware Heaven

And so combining results of both reviews for BF3 at Eyefinity resolution (which is the focus of my next upgrade), I can see how one 7970, versus two 580s, versus two 7970s would do under my desired conditions:

5760x1080 0aa 16af Battlefield3
-------------------
26 Avg: Radeon 6970 OC (2GB)
34 Avg: Powercolor 7970 (3GB)
36 Avg: XFX R7970 Black Edition (3GB)
NA : GTX580 (1.5GB) (not possible without SLI)
36 Avg: GTX590 (1.5GB) (2xGPU)
44 Avg: GTX580 (1.5GB) (SLI)
45 Avg: Radeon 6990 (2GB) (2xGPU)
65 Avg: Powercolor 7970(3GB) (Crossfire)

I bet if they had turned up the AA at Eyefinity levels the 3GB vram would have made even more of a difference, also I wonder if they had used 580GTX 3GB models for the SLI if it would have helped...

So I think this makes up my mind that two 580s for Eyefinity is not a good value compared to two 7970s, so I mainly need to wait to see if Kepler will bring new game for Eyefinity otherwise one 7970 now and then one somewhere down the line for crossfire seems to be a good approach.

My current crossfired 5870s are great but the main problem is the 1GB VRAM is easily used up at Eyefinity resolution with any AA on.

Nope, 7990 will be Dual GPUs,

7970 Eyefinity 6 Will be Single GPU with Double the Memory / Bus / Buffer to account for Higher resolutions, and All Display Ports.

Reference 7970s from multiple brands back in stock at NewEgg without much price markup, maybe $10 more for Sapphire than the first round of stock... Wish we had more Kepler details other than that one rumor about it winning this round on all areas.

Still waiting to hear how the 7970 does in FSX too... The couple of DX9 benchmarks in reviews have looked pretty good compared to the 580 and 6970 and 6990... But still a big amount of money to gamble without more info.

FSX's problem is Coding.. not hardware..

Just look at how Lockheed bought a commercial FS license from MS and Fixed 98% of their problems w/ textures and frame rates.
