webbs hill, no, I'm not struggling anymore with Win 8 - I've used it for my DAW until I upgraded to Win 8.1 and both of them have worked well. Like mudgel, I find the Win 8.1 is very smooth, even more so than Win 7.
I originally did a fresh install of Win 8 and really tried to make Metro work for me... that's the only point where I struggled. Metro is a different design environment but I wanted to be open minded enough to see if it was the way of the future - after all, one would assume that Microsoft must have spent big money testing the interface. So I gave it a try for a couple of weeks, but I don't use a touch screen and Metro was just too inconvenient - it got in the way too much. So I installed Classic Shell and Win 8 worked as well for me as Win 7.
When Win 8.1 became available and I decided to upgrade, I again did a fresh install of Win 8 then immediately upgraded to Win 8.1. I'm running Sonar 8.5, X1 and X2 as well as Samplitude Pro X and everything works very well.
If you give Classic Shell a try, that may take care of a lot of your struggles - Metro is a pain but the operating system works quite well. Good luck.
