The "Best" I have seen is the MSI K8N Neo Platinum. It is coming out soon, uses the new NForce3 chipset, and has loads of features: integrated USB and Firewire, integrated audio, mixed-mode SATA/IDE RAID, gigabit ethernet w/integrated firewall, and it will mow your lawn.
Ok, the last one was a joke.
