You're a bit off there.  There are uses beyond gamers for the newest cards, and as much hope as I had for the GTX 590, I think nVidia missed it too.  The answer is GPU computing.  The way I see it (I may be myopic), is that $700 for a GPU is cheap for the computational performance.  Sadly, the GTX 590 under performs because nVidia was worried about noise & power more than FLOPS.  As far as I'm concerned, I'm just going to buy banks of cards and put them in a room where I can't hear them.  So, despite weeks of waiting, we'll be going with the GTX 580 as it beats the GTX 590, Radeon 6990, and Radeon 5970 for our uses.
