One of the primary reasons to buy a lower-end card is the overclocking potential and the performance that it will unlock.
The HD6790 was able to be pushed all the way from the default core speed of 840MHz all the way up to 985MHz on the GPU. Impressive overclocking performance.
Thanks to the greatly reduced capabilities of the underlying GPU, even with out overclock everything remains cool with the HD6790 maxing out at 69°C.
Of primary importance for us is that this performance doesn't come at the cost of fan noise, with the card being one of the quieter AMD ones we've tested recently.
