Bit-Tech posted a review on two retail Intel SLI boards, one from Gigabyte and one from MSI.

Both of these motherboards are very appealing to anyone considering an Intel-based gaming rig - they're packed with great features and with a performance at the very top end on all accounts. Watercooled, the potential is huge, as Prescott processors can go far when kept cool enough, so coupled with a pair of NV4x/G70 video cards in SLI you could have both a fantastic workstation and gaming rig in one. A low profile waterblock for the southbridge would ease some of the heat worries that we have related to the C19 southbridge.
