OCC has published a new review on the AMD Phenom II 720 and 810 AM3 CPU's

With the new line of Phenom II processors anticipation and expectations are growing. The previously reviewed Phenom II 940 was a beast of a processor, though it only supports DDR2 memory, so there is not any room for expansion into the faster DDR3 market. The new AM3 processors tackle this situation and allow you to run the best of both worlds with DDR2 and DDR3 when the AM3 motherboards are released. When it came down to numbers I was surprised at how well a Triple Core processor was able to jump on the heels of some of the Quad Core processors and sometimes even taking the lead in the video benchmarks. Quite honestly, I did not expect this type of performance from a CPU with fewer cores. Overclocking the Phenom II X3 720 is quite easy since it is a Black Edition processor with an unlocked multiplier. I had little trouble getting an almost 1GHz overclock with a combination of the multiplier and the bus speed.
