Btw, does anyone know how come that GTX460 is compute capability 2.1, and newer few month newer GTX570/GTX580 only compute capability 2.0? Is nVidia going backwards???

Compute capability mainly differentiates 2 things, The instruction set & compute geometry. Although they have the same instructions, 2.1 as used in the 460 is different to the cuda core configuration used in the 470/480/570/580 , which is 2.0. Basically the 460 has extra warp schedulers & a few minor differences, while 2.0 covered the complete original Fermi design.

Thanks. I knew that 470/480 were "older" design then 460, however I (wrongly) assumed that 570/580 would be at least same or newer design then 460...

It's only *slightly* more complicated by things, in that the original full Fermi design is for supercompute, whereas the 460 strips some stuff out & adds other bits to make games go faster. The 570/580 is a 'newer' design, but has the full original Fermi layout, with the 460's memory controller & power enhancements, none of which relate to the compute geometry being optimised for games.

Notice 'slighlty' more power consumption on my top two rigs after the update........
Maybe a couple percent.....
But, that equates to more crunching.
Thanks again, Jason.

For Win 7 64, the new driver is working smoothly. Like Mark said, there is a slight increase in power usage. I migrated up from 260.99. I have no ill side effects.

Thanks Steve....
Good to know that your results were the same as mine.
