The new SB750 Southbridge sees some fundamental shifts from the SB700 which cured USB woes of previous ATI Southbridge chipsets. As mentioned earlier AMD's new Advanced Clock Calibration is supported by the new SB750 which allows for much better overclocking when it is paired with a Phenom processor. AMD hasn't given the deepest of details on this unfortunately and again we are pressed on time to go over even what we do know but in short in our overclocking experience it seems to work well. We bested our overclocking records we achieved with Nvidia's 780a reaching 3.2GHz on the Phenom 9850BE and 3.4GHz on the 9950BE. Any more was a non-possibility and as always results may vary with overclocking.


The 790GX seems to be a good follow up to the 780G and gives AMD another boost in edge in integrated performance. Hybrid Crossfire was interesting at the 780G launch but here it shows it's real potential and fully kicks in more than doubling performance at times in games that support it. A higher-end discrete card will always come out on top in performance but a 3450 can be had for only $38. Unfortunately as we mentioned we didn't have time to test a lot of new features in the 790GX but we will be visiting ACC, power consumption, and more in the future. ACC definitely has a lot of potential but we want to stress test the CPU and make sure it can handle those higher clocks.
