Well, when it comes down to the wire, apples to apples, the DDR3 memory support does give the AM3 processors a bit of a lead. In just about every test there was an increase when using a 790GX based board with DDR3 memory support over DDR2 memory support. If you are in the market for a new system, then I highly suggest going the AM3 route. However, in my opinion, if you are already running a strong DDR2 based AMD system, then the cost does not justify the minimal increases that you will currently get. All of that aside the MSI 790GX-G65 is a rock solid board with great features that will make any enthusiast smile. The overclocking on this board was very easy and has been one of the stablest I have seen with minimal tweaking. The added ability to overclock using hardware dip switches will allow even a novice the added joy of pushing their hardware beyond the limits.
