Ok guys!!! 80% of the hardware tested for this card failed miserably, so take the 20% (that probably barely worked) and paste it together for a new one!
The only reason NVIDIA is "handpicking" the GF110 GPUs for the GTX590 is because they pretty much have 0% power variation that they can play with in these cards to make them stay within the spec. The whole issue with the Fermi architecture was that it is such a complex design that it is extremely easy to attract electrical leakage because there are so many highly sensitive parts so close to each other.
The original GPUs were pretty much at bare maximum threshold for leakage, thus they had to delay them for so long to try to reduce it with optimizations rather than ditching all the work they spent on developing the architecture to begin with and creating a new one instead. Hence, this is the reason why the GF100 cards (GTX470/GTX480, and later GTX465) came out so late. And even those cards were "just enough" to be reasonably useable without major issues. This is why they spent more time optimizing the leakage and creating the GF110 GPUs (GTX570/GTX580) later on. And even on top of that they had to add the power limiting features to be qualified to fit the spec properly because they had to raise the performance of the GPUs in the new generation (FYI, disabling the power limiter brings the GTX580 out of spec).
Now although both the GF100 and GF110 GPUs had leakage issues, the cards themselves had a lot of headroom to play with to fit into the spec so they didn't have to "handpick" GPUs. With the GTX590 this will not be the case, they are planning to design the card with as power as possible that they can fit into 300W. Unfortunately, this literally leaves no headroom for leakage so they are pretty much forced to "handpick" the GPUs. And by handpick, that means they must manually test each GPU to see how much leakage it suffers from so they can pick the one with the smallest amount to use on these cards. You can imagine this process will take quite a long time so there's also your answer to why availability will be very limited. There are only so many they can put out at one time.
I hope this backstory helps fill you guys in on the reason why the GTX590 is going to be a very special card for NVIDIA.Edited by Open1Your1Eyes0 - 2/3/11 at 6:20pm
