No. I'm running a FX60 and 4400+, both socket 939 with DDR3200 ram. (2GBs in each machine)
I'll have an AM2 4200+ up and running tomorrow or Sunday. I'll be putting a Phenom in the AM2 system when the price is right. I've got about $150 in it at this point.
So I will not be slowing down anytime soon.

I welcome the competition though.
