Finally some good hardware news from NVidia

Perhaps a good replacement for the 260.
Added - When I say as a replacement I meant as a alternative.
To physically replace a 260 getting 7000PPD with a 460 that gets 10,000PPD for the same wattage is not a great decision.
$200, about 120 more stream processors, more memory for a couple of bucks.
Low temps, reports about 10-20 fewer watts than a 260.
Two cards for $400 gets you 672 stream processors, way more than a GTX 480 for less money.
Stream processor cost ($/SP)
460 - 59.2 cents/SP
465 - 71 cents/SP
470 - 73.6 cents/SP Updated 66 cents per latest NewEgg ad.
480 - $1/SP
Watts/SP per the article
480 - .877 watts/SP
470 - .817 watts/SP
465 - .99 watts/SP
460 - .82 watts/SP
So the last spec shows the 460 has the efficiency of the 470 at a lower startup cost.
It comes down to what you want to spend, how much heat you want to deal with, how many slots you have.
The Asus model has voltage tweak, leave the speeds alone and undervolt the sucker for more efficiency.

I'll run the numbers from bit-tech later.
Quote From the Stanford forums:
GTX 480 HC ----- 1802Mhz / 2002Mhz ------- 18,786.22 ---- (257.15 Beta)
Total System Wattage Peak: 879watts (SLI GTX 480's & 980X @ 4.6GHz)
18,786.22x2 / 879 = 42.74 PPD per Watt
GTX 480 HC ----- 1789Mhz / 2124Mhz ------- 18,173.8 ---- (257.15 Beta)
Total System Wattage Peak: 857watts (SLI GTX 480's & 980X @ 4.6GHz)
18,173.8x2 / 857 = 42.41 PPD per Watt
GTX 480 HC ----- 1644Mhz / 2048Mhz ------- 16,470 ---- (257.15 Beta)
Total System Wattage Peak: 789watts (SLI GTX 480's & 980X @ 4.6GHz)
16,470x2 / 789 = 41.74 PPD per Watt
PPD is good but it's no Intel 32nm hex core. IE I can't get too excited about it. Also mentioned is that anything that uses 100% CPU will lower your PPD. No mention how much CPU the GPU is utilizing.
