well, seems win 8 is working better for this prog Right now HD 7970 ghz edition, under win 8 it gets 640mhash with bitminter web prog and win 7 gets 530-580mhash.

love this simple prog very much and hope after asics will hit, then it'll support litecoin too (or make new version for litecoin), cause I need something for my VGA-s
