China is most of Asia But they are reasonably popular outside of china as wellBy Asia you probably mean China
No. It just needs to be a chipset thats supports PCIEbut if I want to put in a 7800GT graphics card, does the chipset have to be nforce4 or something like that? I'm pretty much lost...
Yes. Although arguably you could hack the NF4U to a SLI model as well)To get an SLi setup for videocards you need the nforce4 SLi chipset correct?
SLI and Crossfire are different things (i do know what you mean but its a somewhat important distinction). I believe Via also has a similar idea with their K8T890 chipset but i dunno offhand (unless you mean the NF4U-->SLI hack)not necessarily, all that matters is that the motherboard is stated as being SLI or crossfire (if you're gonna take the ATI route) compatable
