Recently, two nforce4 motherboards were released to the market: the GIGABYTE "GA-K8NF-9," which is a standard nforce4 mobo @ $149 + shipping at newegg, and the CHAINTECH "VNF4/Ultra," which is an Nforce4 Ultra mobo @ $129 + shipping at newegg. More than likely, one of these two boards will be in my next PC. But which one should I choose? Could someone explain the differences between nforce4 and nforce4 ultra? The only difference that I could see from looking at newegg was that the Ultra board doesn't have any firewire ports, but I could always just buy a PCI card for that.
