In interpreting the results on the boards, we see that the Dynamic Range and Noise Levels on the eVGA 650i board does ok for itself compared to some of the other boards represented here, but it certainly could be better. Since the greater the dBA the better, we can see that it falls behind a few of the other boards. We can also see that when it comes to the THD and IMD percentages, the 650i Ultra does very good compared to the other boards, since lower percentages mean better audio. Any of the boards audio will probably be fine for most people, even for gaming and movies. But if you are a die hard audiophile, you will likely get an add-on card for the best sound that is available.
