Is CrossFire micro stuttering a hardware or driver issue?
I'll have a Radeon HD 7970 GHZ Edition now, if it's a driver issue then I'll buy a second one when it's fixed.

Or is it both a hardware issue and driver issue, and the stuttering will be fixed a bit with new drivers in the future, but not completely?

both are basically doing (or should be doing) the same thing as far as i understand it, so it should be doable via drivers alone. How well they manage to get rid off it remains to be seen but the hardware solution nvidia is using isn't exactly perfect either, they still get some stuttering sometimes. Hardware implementation is better thou since it doesn't require any extra processing to be done in driver level so it is easier on the cpu. That said, drivers are easier to tune for different games than hardware :p

I don't think anyone here can tell you for certain whether or not it's a hardware or driver issue. However, it is fixable with driver updates and is slowly being addressed, so I'd hang on. (I'm basing this on my experience with previous generation crossfire)

they are working on it, the latest 13.8 beta2 drivers almost completely fix the stuttering for dx10/11 games in single monitor setups, support for dx9 games and multimonitors is coming later. It seems to be alot of work to fix it so it is taking some time... but it looks promising.

So they can fix it in the drivers by frame pacing, but it can also be done on hardware level which would be the next step in the process really, maybe 2 gens from now perhaps. Nvidia has been working on this for a lot longer and have implemented this on hardware level already.

But will the stuttering on the 7970 GHZ ever be fixed with drivers completely? Or do you need hardware changes to fix it completely?

You'd have to ask AMD that. It is possible that it can be fixed completely, whether or not they'll do it though is another matter. I suggest you don't base your purchase on whether or not AMD will fix it as these things can take forever.
