I built myself a gaming PC about two years ago. I've been an AMD supported for decades, so I went with the best CPU AMD was offering at the time. Two years later, it's still the best CPU AMD offers.
I remember the heyday where AMD actually overtook Intel. Their CPUs were actually better and cheaper. That's no longer the case, but (at least when I built my gaming rig) I was not willing to pay 50%+ more for maybe 10% higher performance, so it was still AMD for me.
The important thing, though, is that we need competition in order to spur innovation. Before AMD started nipping at Intel's heels, it was all about the MHz (and who could get to GHz first). After that, we started seeing CPUs with more cores and better threading and all the good stuff. I hope Ryzen makes Intel very worried - worried enough that they innovate the hell out of their CPUs. I also hope Ryzen makes AMD enough money that they can continue to innovate, and continue to compete with Intel. Because when that happens, it is we the consumers who win.
