Not using any watercooling or LN2. The Gigabyte GA-965P-DQ6 with our ES X6800 runs at an amazing 466MHz FSB with a multiplier of 6. Imagine your RAM is running in SYNC at 1:1 to your CPU!! That is at default voltages with PCIe fixed at 100MHz. This is just an initial test, I am able to POST up to 6 x 490 but it isn't stable to go into WIN XP.
