I'd say the K8N-E Deluxe for several reasons: native gigabit Ethernet (of no use to some people, depends on the situation), integrated firewalling, PCI/AGP lock for mad overclocking goodness (NOW we're talkin'

), and you should be able to twiddle your settings from Windows, using the nVidia system utility. If it matters to you, it also has six SATA jacks (four using a PCI SATA controller, two native).
