Asus offers a Athlon64 series CPU board for the FX series processors from AMD.  Here is a review of that board.
There is very little to wish for apart from the already included features and this makes the SK8V a very good base for a high-end PC. In terms of BIOS and software features Asus has added a few tweaks of its own including voice diagnostics (yes, the motherboard will tell you what has gone wrong), automatic fan adjustment and you can even create your own BIOS logo.
