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
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...
