I am presently using an Asus A8V Deluxe with an Athlon 64 3500 and an ATI X800XL AGP video card and it works well. Plan on upgrading to an X2 processor when prices come down and HTPC s/w that uses dual processors becomes available. The A8V Deluxe will probably be the last Asus 939 motherboard with an AGP card slot. Therefore, I am also considering the Asus A8N-E that uses the Nvida chipset and has a PCI-E graphics card slot. The PCI-E version of the ATI X800XL is only $268 from mwave.com.
