Hi there
I tried these drivers with 7600 gtx gddr3, also overclocking DDR3 from 1.2 to 1.35 (leaving GPU@430)
No heat increase. Even having watercooling and an excellent water block for the 7x00 series, if this was a software bug, the overall temperature should rise one or two degrees..
Also the drivers gave me no crashes. And no speedup in the graphics (what a shame..

).
Cheers
