I am one of the FX 8150 Bulldozer owners, i got it a few weeks back with an MSi 990 FXA-GD80 board. It definitely has shown its potential on the benchmarks in a few areas, and i am sure a few bios updates/ patches down the road it will be fine. I have always gone for what is Now, rather than what was good last year!
I am experiencing a few issues though with drivers and software updates, i didn't do a full re-install when i fitted the new stuff and i am guessing there is conflict, thought i might have got away with it
Full re-install on the cards i reckon.
