As soon as the new stable kernel has been released by Linus Torvalds, i downloaded them and install it on my workstation few days ago. It was a nice release, and one thing i would like to test is the new EXT 4 SMP scalability and also further performance improvements after they removed the BKL (Big Kernel Lock) and many other patches from the kernel developers. At that time, i didn't install it on my desktop first, since i'm not really sure whether the current NVidia driver already supported this new kernel or not.
Since few days ago NVidia launched a new driver, 270.41.19, i quickly downloaded this driver and then compile the new kernel on my desktop and at the moment, i'm compiling it on my laptop as i'm writing this post. The new NVidia driver already have support for Linux Kernel 2.6.39, so if you are curious about the new kernel and you are using NVidia, go for it
Here's the result on my workstation:

and here's on my desktop

and lastly, my laptop
