Here in Halo the 8N-SLI and AA8XE both fall significantly far behind the leading two boards. The more I look at the gaming results, the more convinced I am that the PCIe timing is set up sub-optimally by default. The 8N-SLI came in almost 10% slower than the leading board.
Jedi Knight 2
The 8N-SLI Royal did reasonably well here, only 2.3% slower than the leader.
