Well the Hydra engine seems to be true (first out on Intel x58 smackover), with Lucid Hydra having one of the main sponsors being: Intel

I can't find the article but it seems RD890 will support 4 x PCI-E 2.0 x16, unlike todays RD790(790FX) which can "only" support 4 x PCI-E 2.0 x8 or 2 x PCI-E 2.0 x16.

Iam definatly getting a AM3 platform when RD890 and SB800(SB850?) is out, atm DDR3 just seems to be a waste for AMD systems.
