The GTX 470 was a high-end card during its time, being the second-fastest single-GPU offering in the GeForce 400 series. It's still a very capable card, but it has been supplanted by cards with similar (gaming) performance with lower power consumption. However, it's still a very strong GPGPU and crunching performer.
GK104 should outproduce GF104/114 in terms of GPGPU performance, but it will likely be behind the GF100/GF110, as this is not a card purposed for GPGPU processes. When GK110 comes along later this year we should see a GPGPU MONSTER.
You can check out my GTX470 vs GTX570 comparison from a year or two back to give you an idea of its performance relative to last year's #2 in nVidia's lineup: http://www.overclock.net/nvidia/895590-gtx470-vs-gtx570-comparison.html

That is still my favorite non-reference heatsink to date. They took a step backward with Twin Frozr III as far as I'm concerned.
