Will be interested to see what you are able to find out.

Well the good news is it hasn't broken anything :D
Looks pretty similar so far, apart from a nicer looking installer, added support for the the 450 cards and some minor bug fixes doesn't look like a hell of a lot has changed
Gonna let the last 10 or so tasks I have run through then run some comparisons through using test wu's to see how these stack up against the 258.96 drivers
msattler:
My bet is the main reason for the release was the 450s.

... and possibly sneaking in Cuda 3.2 support before the programming tools are released.
Ghost0210:
So have done a couple of quick bench tests with both the 260.63 and the 258.96 drivers:
260.63

Looks like overall 260.63 is faster by some margin! All wu's ran 1 at a time on my GTX465
