Not surprisingly, GeForce GTX 690 demonstrates respectable FP32 performance. However, its FP64 throughput, artificially capped, is far behind the capabilities of even one Radeon HD 7970.
Unfortunately, Nvidia’s 301.33 driver appears to break support for the OpenCL General Purpose Bandwidth and Cryptography tests, which previously worked just fine. I think it’s pretty clear, though, that the company intends these as gaming cards and hopes to separate out its compute-oriented products.
That’s good news for AMD, since its GCN-based Radeon HD 7000-series boards seem well-suited to both 3D and compute applications.

As a case in point, LuxMark 2.0 shows the Nvidia cards all underperforming current- and last-gen AMD boards, with the Radeon HD 7970 in CrossFire throwing down huge sample/sec results.

6990 aren't that hard to find. Back in January before the 7000 series came out, you could easily pick one or two up. I am pretty sure in 6 month, the 690 will be easy to grab.
Also the design of this reminds me of my old leadtek 5900

GTX 590 launch...
GTX 580 launch price: $500
GTX 590 launch price: $700
Difference: 140%
Now today GTX 690 launch...
GTX 680 launch price: $500
GTX 690 launch price: $1000
Difference: 200%
So, is it just me or is nVidia really gouging on the price here?
Why the hell else would they be charging an additional 43% more than their last dual GPU launch while using less silicon?
Come on AMD, we really need some more competition here.
The only use case for that much graphics hardware is excessively high multi monitor resolutions like 6k x 2k in 3d. AMD doesn't need to invest in new PCB designs to make a dual cpu GCN chip yet because the demand is so low.
