XFX just posted a bios update for the 5970 on their website.
I just flashed mine and noticed that manual fan speed now works.
It doesn't seem like they fixed the powerplay issues with multiple monitors.
That is, if you try to overclock, you get bad flickering because the memory
clocks are going down to 300 on both cores, or at least I think that's the problem.
If you have only 1 monitor connected, overclocking works fine.
