Yes, in some situations, at stock speeds - but the 4100/4170 can crank out the Ghz, even on air (I am using a 5 year old air cooler, from my first socket AM2 rig - getting a 4.5 Ghz rock stable PC)
However, I was dissapointed in the bulldozer bigtime (bought the AM3+ board prior to the launch), was hoping it would give intel a run for their money....but alas, no.
However, as a platform, it is a very good value build. IMO it is better than an Intel Build for the same $'s.
(with a MB with good power options, OC ability, etc..) This is in Canada, anyway ( not sure on the cost of things in the USA).
I am not an huge fan of AMD, prefer Intel actually, but on the low end (when looked at as a whole), I still think AMD has the best $ value IF you overclock.
Right now, I have a PC that can run anything I throw at it, that would cost ~$700 to build (no monitor).
Sure it is not the fastest thing by the numbers, but it feels fast, and is never sluggish.
