So the thread says going from 134 - 330.. I have yet to see any sort of leap from using other miners or rpcminer at default.  I realize that people are working on functions to try to improve that and their efforts are greatly appreciated but, I think all of us would like to see a nice bump in our mining with our nvidia cards.

thoughts?

134 MHash/s to 330 MHash/s is for a Kepler K20 or the consumer version Titan. A big jump with old NVIDIA GPUs is not possible. CGMIner is very near to the maximum power of old NVIDIA GPUs. Al GPUs before Titan has no funnel opertor and need 3 operation for a rotate, the new one need one operation.

Ahh ok sorry my bad, thanks for the clarification.. so your saying the 690's and below will still be somewhat limited or same speed with out much boost?

I have a gtx 680..

GTX 680 IS a Kepler..

Onyl Kepler equal or higher than titan GPUs. GTX680 is K10 architecture, you can say it is a better fermi. K10 has no funnel operator :-(. Thay have the same amount of 32Bit registers and a lot of opration have the same speed  than a k20 but the importend operations are not available.
