Yep, pretty much just wrong. They would be correct if you wanted to Crossfire the cards(that you need a Crossfire capable motherboard but it is rather like saying you need a socket 775 motherboard for a socket 775 CPU, i.e. so obvious it shouldn't need said) but for a single card it makes absolutely no difference as long as it is PCI-E(preferrably PCI-E 16x). deadeyedic30 is currently using an Nforce4 based motherboard with an X1900XT as he says and there are a great many more on these forums who are using similar systems without any problems.
