I'm planning on getting the ATI All-in-wonder X800 XT video card/tuner which is AGP only

They don't make a "great" PCI-E vid/tuner board. AGP is ok, but I want to ditch my ABIT board and go with a Nvidia chipset board for the 939 CPU's but I'm having trouble tracking down a good one. I have found the DFI NF3 Ultra Lanparty online but they are hard to come by - Newegg, Zipzoomfly, etc don;t even carry them. I'm womdering why.
Any other suggestions. I'd like to OC a little but really I'd like a good quality, stable board. I think the AV8 is too flaky.
