Replacing Everest in our labs is AIDA64. This new testing suite is from the core development team from Lavalys and continues that tradition. The guys have thrown in better support for multithreaded CPUs as well as full 64 bit support. We use this to test memory and HDDs for now, but may find ourselves opening this up to other areas of the motherboard.
Comparing both SSD and USB 2.0 performance between the chipsets, you can see there's a clear difference with the 990FX based Crosshair V Formula offering strong performance in both tests.
