Playing around with core and memory clock settings individually, I see that memory clock plays the most important role.
--texture-cache setting did not affect performance.
--interactive 0 gave me additional 10kh/s
I ended up using 1012/880/2350
I have tried out CudaMiner with my GUI front-end,
Crypto Miners in Tray, and it is fully compatible.
Christian, I am sending 1 LTC your way as a thank-you token.
