DO NOT GET THE BULLDOZER FX CPUS from AMD!!!
sure they may be dirt cheap but they from the reviews and tests they suck, they suck bad, heating is a big issue and instability in performing real world tasks
better get the NEWER(almost FIXED) PILEDRIVER FX CPUs that has addressed most of the issue that plagued the Bulldozer CPUS but still not as good as i7 CPUs
the Trinity CPUs long with the new FX series are all based on the new AMD architecture
