GIGABYTE GA-EX38-DS4 for dice?

[ghost_recon88]

Looking at grabbing a new dice board, I see the Asus Commando can easily get over 600MHz FSB pretty consistently, but I'm looking for something with dual PCI-Express 16x slots for maybe a little X-fire action under dice as well :D I'm looking at getting this board here,

I've seen it hit 580MHz FSB with stock NB and CPUvtt settings, but I'm wondering if anyone has taken this mobo over 600MHz FSB? Also I see Gigabyte released an X48 board with very similar stuff as on the X38 board.

Any chance of flashing the X38 to X48? Thanks :p:
