Bit-Tech published a comprehensive review of AMD's new Phenom II X4 and X3 socket AM3 processors

Finally, AMD is mostly lacking stock - right now, even a few days after release you still can't buy any of these CPUs - that's a mirroring of the Athlon X2 7750 and Phenom II X4 940/920 launches where actual product was unavailable for several weeks. We seriously hope AMD rectifies this soon, because it only gives Intel more chance to fill the gap.
At the end of the day, the Phenom II X3 710 is a superb price at a shade over £100 for a pretty high performance multi-core CPU (certainly better than the original "cheap" triple-cores) and dropped into an AM2+ motherboard the Phenom II X3 720 Black Edition affords some much needed consumer choice for inexpensive, multi-core overclocking fun.
