The ASRock 880G Extreme3 was a good performing board. We saw solid performance for most tasks with a few exceptions that were more related to the CPU used than anything else.
We did have some issues with memory and getting the voltages dialed in right for the type of memory we were using. We also saw the IGP have problems with overclocking. We have a feeling that this will be resolved with a future BIOS update. For now, you can get good clocks on air cooling with little trouble if you are using an Add-in GPU.
At only $105.99 at the time of writing over at NewEgg.com, the 880G Extreme3 is a good deal. When you add the performance with SATA 3.0, USB 3.0 and Tri Crossfire support, the pennies do add up.
