We have compared the two boards at 3200MHz with 800/1200MHz DDR2 and 1066/1600MHz DDR3. As you can see the differences are very small. DDR3 is sometimes a litte bit ahead, but at what cost?. Even the DDR3 overclocking modules are about 3x more expensive compared to DDR2. The charts shows DDR3 does not justify the costs, DDR2 is still a match vs DDR3, even 2000MHz DDR3 memory won't make a difference.
