comment GPU user experiences
My 3+ year old MacPro desktop with ATI Radeon HD 4870 runs your code in 0.077 sec. My 2012 MacBook Air with Intel HD Graphics 4000 runs it in 0.110 sec. Both are running MMA 9.

Seems like a good idea.

comment Why does Mathematica struggle with solving this equation?
@OleksandrR.: Actually, I see your point. I suppose I was incorrectly expecting the same answer as NSolve provides, but the message from Reduce is pretty clear.

comment Why does Mathematica struggle with solving this equation?
I think Reduce is close to giving you the correct answer because -16.9154*-0.405465=6.85862, but for some reason it can't get rid of the complex value (0+2PiI). I would report this to Wolfram as a bug.

@whuber: Of course you're right. I didn't read the question too carefully.

comment What does # mean in Mathematica?
You may find the Mathematica Documentation Center helpful for questions like this (you can just type # in the search field at the top and it will direct you to an explanation). In any case, here's a web version of the documentation: reference.wolfram.com/mathematica/ref/Slot.html
