nvidia GTX 750 Ti - people are reporting 250khash from only 28W and 300khash from 38W
Wow, that would be 8-9 khash/Watt, so 2-3 times better than ATI. Almost as little as the GRID asics.
And the card costs less than 200 dollars? I have no experience with Nvidia cards,  and the 750 Ti is not yet in the hardware comparison list. Does anyone actually know about such a list with also all the Watt consumption values?  
Please post more such information. Thx.
I just ordered 2 of those GTX 750 Ti's. Will get them next week. If anyone wants to play with them on teamviewer: let me know! Smiley
I did read that 265 khash on 28W was possible with CudaMiner. Can't wait to put 5 of those in my rig!  Grin
Cool. Looking forward to seeing your results!  
Do you own a wattmeter? If not, get one now, they are cheap.
I don't trust the internal power sensors, please measure the Watt differences on the wall plug (between: no card, card disabled, card full power)

thx

Just inserted them on my motherboard. Both cards do around 260 khash on cudaminer.

My system with 2 cards in idle: 75W.
Both cards full power: 200W.

So each cards around 62/63W and getting 260khash/s.

Edit: I tried to run it with 1 card:
My system with 1 card in idle: 62W.
1 card full power: 128W.
