I did, a year and a half ago. I decided upon FX-8320, as for me, more cores was better. In my PhD I'm doing automatic parameter tuning of optimization algorithms, and I thought it would be handy to have as many cores as possible also back home (the actual runs are of course run on a monstrous computation server somewhere in the basement of the university). To have 8 separate cores has proven to be handy every once in a while. Just yesterday I did some parameter tuning on a machine vision side project.

Back then the difference in bang-per-buck was even more striking than it is now: http://paulisageek.com/compare/cpu/

Also, by choosing AMD I avoided the minefield of missing virtualization and overclocking support of some mid level Intel models.
