Nforce all the way. This is my third nforce box, 2 Asus & an MSI. All have been perfectly stable and reliable. As Bloom said, memory bandwith is better with 2 sticks but you can always add another later. I wouldn't trust online Bios update. Asus Nforce 2 in sig has an easy safer method. Download the Bios file to a floppy. The flash utility is built in. Press F2 on boot and type in the name of the BIOS file. It will save a copy of the current BIOS and install the new one. It doesn't get much easier than that. Another nice feature of the Asus A7N8X DLX is that it locks the PCI bus at 33 and the AGP bus at 66 so you can more safely overclock.
