    Put it to the test and let us know the outcome.

    Thanks for the heads-up Lou! Let's see what the review say...

    Updated yesterday, so far about 50% slower than Cuda 5.5 with web drivers. Quick test with cudaminer confirms about 40-45% drop.

    Which graphics card, v0n? Maybe it's optimized for Kepler class GPUs?

    GTX 660 and GTX 470.

    Using cudaminer on GTX 660 in benchmark mode:
    196kH/s with CUDA 5.5.47 and stock Maverics drivers
    212 kH/s with CUDA 5.5.47 and Web drivers 331.01.01f02
    Struggles to pass 141kH/s with CUDA 6.0.37 and drivers 331.01.01f02.

    Installing 5.5.47 back pushes benchmark up to 169 kH/s but won't go back to figures from before installation, something somewhere has been overwritten, maybe reboot required.

    I just installed CUDA 6 on my early rMBP (Geforce 650M) and CUDA-Z's single precision GFlops go from 300 to 260. What's interesting is that rebooting to my Windows 7 BOOTCAMP partition I get 400 Gflops (the same as with CUDA 5.5). Is NVIDIA intentionally hamstringing the Mac since Apple dropped them in the nMP?
