Whats with the continual bashing of gigabyte? Most motherboard manufacturers are up and down, fluxuating in quality where as gigabyte is always the same above average quality everytime you buy one of their boards. I remember when everyone used to take their dumps all over DFI my how the world changes =/
the k8nf-9 is a great board..
the a8v is a piece of crap (via chipsets suck)
the only other board that i might switch to (from your list) would be
-(Sckt939)GigaByte GA-K8NXP-SLI nForce4 SLI Chipset Dual PCIE MB w/Gb-LAN,USB2.0,IEEE-1394,&7.1Audio (im very partial to this board)
-(Sckt939)ASUS A8N SLI Deluxe nForce4 SLI Chipset SATA RAID Dual PCIE MB w/Gb-LAN,USB2.0,IEEE-1394,&7.1Audio
diablo, my k8nxp-sli will out-overclock your dfi anyday =p
