Latest drivers (NVidia and ATI)
TouchuvGrey:
i just downloaded and installed the beta 266.35 drivers.
Have also downloaded, but not installed the CUDA Toolkit
3.2 ( 64 bit ). Is their anything i need to do to insure that
3.2 gets installed properly ?
i'm familiar with updating nVIDIA drivers but only
did 1 CUDA and have forgotten how i did it.
Richard Haselgrove:
I've only ever downloaded and run the driver installer package. I usually turn off BOINC entirely while I'm doing it - disable autorun at startup - because there's often a reboot involved: once the reboot has completed and everything is running, I check the driver and CUDA versions in NVidia Control Panel, and if they match what I'm expecting, I reckon it's safe to fire up BOINC again. Never been let down yet.
The only conceivable thing you could need the toolkit for (apart from developing new apps, of course) would be to get hold of specific versions of the rt and fft DLLs. I did that a few times in the early days, but now that the DLLs are "strongly versioned" (all recent CUDA applications need to have exactly the DLL versions they were compiled for), there's no point in extracting any support files manually.
TouchuvGrey:
As is all too often the case i acted in haste and was less than
clear as a result.
i downloaded the 3.2 toolkit because that was the first
reference i found to CUDA 3.2. Developing apps and needing
specific versions of rt and fft dll's is beyond me.
i am looking to get and install 3.2 CUDA on my machine as
it seems likely that with the newest drivers and my GTX 460 i
would see some significant performane increases.
What is the best way to do this ?

Just install a 260.xx or later driver,
