I've installed the latest drivers for both of them. The problem is the special 3dmax quadro driver which has been enhanced to boost the performance. It seems as it wouldn't load if it detects a geforce card installed (I've tried to unplug the GTX460 and everything went back to "normality")
I've been ...

I'm a 3d max user and I've just added a GTX460 card to my current setup (i7 860+quadro FX580) to test octane.
But now I've got a big problem, after I installed the new geforce card the quadro 3dmax performance driver refused to load, which makes working with Max a pain.
Is anyone having the same ...

Many GTX460 have been released with factory OC so If I decided to overclock myself I can assume it's OK as long as I can keep the temperature within safe limits, right?
Anyway this all was about which card is better for octane: an OC'ed GTX460 2GB or a GTX470 as both are similary priced.

I'd like to know what is more important for a better performance in octane, more cuda cores or less cores but with higher clock speed.
The later is true for gaming (in fact an overclocked GTX460 performs quite close to the GTX470 despite having just 336 cores)
but I'm not sure about cuda ...
