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.
Also carrying XFast USB support, we see that the performance from the Pro3 is strong and offers a nice boost over boards that don't offer this feature. As for hard drive performance, it lines up with the Extreme4 almost MB/s for MB/s.
