X11 is becoming a very popular solution for miners and has two very decent coins under its belt already, Darkcoin and Hirocoin. Kudos to Evan Duffield the original creator of X11.
The NVidia miners are somewhat left out though as there is no Cuda miner for X11 yet. I would like to offer a bounty of 20,000 Hirocoin for a working Cuda miner for X11. This offer is open for the next month and will be reviewed on the 26th March if no Cuda miners exists at that point. The bounty is currently worth 0.8BTC and the price is rising sharply.
Let me know if this is something that you are able to do and want to compete for the bounty. Miners will be validated on nvidia cards in the order that they are submitted.
Here is a better solution and saves you your 0.8BTC.
Why dont you sell the POS nVidia cards on eBay and get a couple of monster R9 290s? Better speed for gaming, better scrypt mining and better resale value (AMD Graphics cards FLY off the shelves. Try putting on on Craigslist at the right price, you will get tons of messages).
Because:
A) My 750tis mine at 50% hash of my 7950s for 25% of the power.
B) Summer is coming, I'd rather not have my 7950s heating up my apartment.
C) Decentralization, be it individual hash, pool hash, or hardware adoption (remember how AMD prices skyrocketed as a result of mining?) is better than a monopoly.
nVidia has NEVER been faster or better at the same price point compared to AMD, NEVER, neither has Intel, again at the same PRICE POINT. The only thing AMD has continuously failed is the Catalyst drivers which they can never get right.
Radeon R7 265 2GB is the direct competitor to the 750ti You are comparing it to 7950 which is not a very good card for mining plus its 2 years old already. Compare to 280x at least thats 10 months old:
The R7 265 costs $150 gets 445 kh/s and uses 150W
nVidia 750ti also costs $150 gets 300 kh/s and uses 38-60W depending on which model you use
User needs are subjective though. I have only had one Nvidia card in my main rig over the past 14 years, and that was the 8800GT, as it was great value for money at the time.
All my other cards have been AMD/ATI as they offered the best price/performance ratio in my price range. I currently have crossfired 7950s in my main rig.
So whilst AMD are winning the price/performance crown, you are forgetting that that crown isn't the be all and end all.
My cards do a great job mining, but are sitting in the mid-to-high 60s doing so whilst being fairly noisy. Heating my flat with them has been great over the winter, but it just won't be sustainable during the summer.
This is where the 750ti power efficiencies come in to play. Yeah, lower hash means it takes longer to recoup my initial cost, but after that, my earnings are actually better due to the significantly lower power usage. The fact that they are running in the mid-to-low 50s whilst being inaudible of my general livingroom noise levels is a MASSIVE plus too.
If someone is happy to endure a slower ROI for the benefit of lower power usage, noise and heat, then the 750tis are the best choice, and that is why some of us would like support for Nvidia to be extended.
