He also claims that the power efficiency will be better than anything currently on the market and will be very good for mining as long as they are able to go forward with the 20nm manufacturing for Maxwell and hit no road blocks along the way.
This seems very exciting for the mining community. If all of this is correct I am definitely going to hold out for a maxwell card when they come out.
I also think that Nvidia will pull off some amazing numbers on the highend Maxwell gpu's when they launch in Q3-Q4. Just looking at 750Ti Khs / Watt it's quite crazy. 45w on a single OC card and pulling 305Kh/s is quite sick. Just to add things up
AMD 7990 - Hash-rate: 1385 Kh/s | Cost: $660 | Kh/watt: 4.6266
AMD R9 290 – Hash-rate: 900 Kh/s | Cost: $400 | Kh/watt: 3
AMD R9 290x - Hash-rate: 880 Kh/s | Cost: $560 | Kh/watt: 2.416
AMD R9 280x – Hash-rate: 725 Kh/s | Cost: $320 | Kh/watt: 2.416
AMD 7970 - Hash-rate: 725 Kh/s | Cost: $350 | Kh/watt: 2.416
AMD R9 270 – Hash-rate: 450 Kh/s | Cost: $180 | Kh/watt: 2.25
AMD 7950 - Hash-rate: 650-700 Kh/s | Cost: $300 | Kh/watt: ~3.25
750Ti - Hash-rate: 305 Kh/s | Cost: $179 | Kh/watt: 6.77
If Nvidia can maintain the hashing performance on the GTX 870 / 880 it will make things quite interesting. My guess is ~1100Kh/s fully optimized GTX880 @ 270w undervolted.

This is my current code.
So now it just booted and my gpu is getting surprisngly hot. It hit 72 in like a minute and it keeps going higher.
Do these numbers/hash rates look right with a 7950 boost? It's hovering between 475-500 Kh.
Im getting ~650Kh/s on my cards:
TC24000, Int:20 1050/1500Mhz
