Doc - it's my primary PC.. the 2.4 GHz single core CPU just didn't cut it for the graphics and other things that I did. Remember, I had a 2.8GHz AMD dual-core that died during the upgrade. 
The spare PC with 2.4 GHz single core was too weak.. replacing it with a 3.4GHz dual-core mad a big difference. My wife has a 3.0GHz single core and does similar graphics work and did not have the same performance issues. Using a 1.5GHz Celeron on my tablet, however, was quite adequate. With a $2 cost difference between used P4-3.0 and 3.4GHz CPUs and a $20 total cost, it made sense to go for the faster CPU.
I've read most of the other articles, mostly complaints and gripes. I had little choice but to use Win-8 first-hand to properly advise clients to its strengths (few) and weaknesses (many). Honestly, aside from some very old software (Photoshop CS-2 and the DVD player), everything else has installed without issue - a positive thing. I'm bugged that some new features that should have replaced aftermarket tools don't work, but the aftermarket tools do. With the addition of the start menu utility to remove the dependence on a start PAGE, the biggest complaint right now is visual appearance and the decrease in usability that results from it, and the stupid Metro apps that insist on running as a full/only screen (WTF??). Jeez - just releasing a couple of themes with higher contrast for office would go a long - LONG way to make Office 2013 usable.
