Retail 3950x's haven't really dropped in price from what I've seen. I bought mine in November, and it was still $750 brand new. You could probably get one for cheaper shopping used though.
I can't personally justify upgrading past my 3950x, not yet at least. And honestly, unless you're a programmer who does a fuck ton of compiling, I can't justify buying anything beefier than a 3900x at best. I usually suggest 3600s to my friends who are going to build, at least if they plan to play video games. For just daily use, something less.
Anyways, I digress. Maybe the 3950x's have dropped in price since November, but not from any store I've found online that I would consider reputable.
