Disk Drive Controller
The system drive controller is an important part of system performance. In most modern boards your drive controller will run off of the PCI-e bus. The PCI-e bus performance can be affected by poor trace layout as well as many other design choices that show up on different boards.
For testing we use Sisoft's Sandra and Everest.
Ok, I am not sure what to make of the results here; we see an improvement in HDD (SSD) performance with the addition of the HD 5870 (along with a memory performance increase), but the HyperPi scores dropped. Something is out of place.

Everest confirms our Sandra findings and would seem to indicate an issue (possibly with drivers) with the HDD controller when using the IGP.
