Yeah the K8N is awesome. If you just want to game, you could get the Chaintech VNF3. It's the same Nforce3 chipset, which I think is the best right now, but with less "add-ons" like firewire, anyRaid, gigabit ethernet w/ built in firewall. You can get it for $70 at mwave.com, definitely the budget choice for Nforce3 chipset. But, let me reiterate, the K8N Neo is the shiznit, hands down best A64 mobo out right now.
