Everything is working fine for me but I haven't tried overclocking yet. Also, I haven't used Vuze or Time Machine yet. I been using utorrent which I like much better. I am buying an external drive soon so I will let you know if I have Time Machine issues. Also, I have been hearing good things about SuperDuper for back up, but not an ideal Time Machine replacement (more of a "complement").
I bought the same motherboard last week and followed the same tutorial. Very helpful indeed, though I do have issues, some not related like Flash crashes I had before, other that are new, like crashes with Vuze, the Console (!), and Time Machine not working.
Everything's fine for you? Is your CPU overclocked? I'm wondering if that's not the problem for me. A memory issue, maybe. I'm checking that right now…
Keep me posted if the problem is overclocking related.
