Hey,
I've been working on a CUDA miner. I've just got all bugs resolved. First hashrate measured on a GTX780 is a meagre 0.7MH/s, but it's a start! More updates here when I make improvements...

Does it mean all Nvidia user need to update and upgrade their ethminer?
I've attached a win64 release binary for those of you who want to test the difference. Might be that on different hardware, the speed difference is different from what I have on the 780. Other OS can grab and build the source from https://github.com/Genoil/cpp-ethereum/tree/cudaminer.
Use the -U flag instead of -G
Before porting anything upstream, I really want to have mined a block on the testnet . During development, I made sure the CUDA miner kept reporting the same results as the opencl miner, but you never know
I'm now mining with CUDA on the blockchain, but with the current hashrate I don't think I'll be finding any block anytime soon.
@PascalVerst The build I attached was for Kepler architecture (Compute 3.5). I'll post one that suport Maxwell better, I would expect it to do a little better.

As for why you only got that and not more, I've no idea. But yeah, with that hashrate you should have got more...
Now does 17.8MH/s on the GTX780.
I'm running GTX750 TI on Win 7.
Normal mining seems to work but at only 1MH/s. Given that stats put the card about 1/3 as powerful as 780 I was thinking it would have been around 5MH/s.
GTX 750 OC (not TI, but no real difference)
Did phone home on benchmark after a while.
The cards power consumption is only 30% when mining so there's still a lot of legs in there somewhere. Also, there is a 3 second pause warning after every work loop. Is that intentional? Sorry I can't be more constructive, I think I'm going to have to knuckle into the material about how mining actually works...
