Buying another X1800 is definitely not a good idea. As for Crysis, nothing really can play it at high res with all the details turned on at ridiculous fps anyway, so might as well wait a little. What game resolutions are you running?

And part of the PCIe 2.0 spec is to be backwards compatible with PCIe 1.1. So don't worry about it. There is no real world performance difference yet between the 2.(I've looked at the HD3570 - and see that it requires PCI-X 2.0 (for the life of me can not find the detailed specs on the mobo - just says it supports PCI-X - dual lanes - for Crossfire mode).
