Thanks for the response...as far as I know it depends upon the pools terms when they pay...for Yiimp they pay out every 3hrs....it may vary with yours...
I was able to use MSI afterburner software to gently overclock my card and get 10% more performance, to go from 3mh/s to 3.3m/hs, but not sure it made a difference...interested to see if anyone is getting better results with similar hardware, somehow.
