Hey Christian,
Are there any other improvements that could be made for scrypt mining with the GTX 750 Ti's with the Maxwell chips? It seems like there is unlocked potential with these cards.
I couldn't find such potential yet.

And face it: scrypt GPU mining will most likely be unprofitable in 3 months, even for the power-efficient 750 Ti's... we're looking to get alternatives working in time (Quark, X11, Heavycoin, possibly Riecoin too)
standard scrypt will be done but there will always be something to mine that will be profitable too many people that are mining looking for something.. just need to think outside the box .. something with a changing alogorithm not multiple will probably prevail as asics cant be made they will just change the algo..
a coin like vtc developers wont be scared to hard fork or whatever is needed to resist them and thats all thats really needed
adding more types of alogo's dosent accomplish anything in the long run
