Memory Tests
ScienceMark 2.0 - Memory Bandwidth

The graph above demonstrates what you're going to see across the rest of the tests. Close performance between two mainboards setup almost identically, with one or the other taking the win depending on test.
ScienceMark 2.0 - Memory Latency

While slightly faster in terms of raw bandwidth, the Gigabyte is slightly slower than the ASUS board in terms of memory latency. Slightly.
HEXUS Pifast

Recoil in abject horror as the two boards perform almost identically.
