AMD-64 and PCI-Express?

[Mark Fuller]

I want to switch to AMD 64bit when Fedora Core 4 is released. I notice Asus
has some new motherboards supporting "PCI Express" on both Nvidia Nforce and
VIA K8T890 chipsets. And, something called "SLI" on the Nvidia Nforce
chipset. (Asus A8N-SLI Deluxe, A8N-SLI, and A8V-E Deluxe)

Does anyone know how Fedora Core 4 (or earlier) supports these newer
motherboards and graphic cards? Will I be ok buying into new technology like
this? Or, am I safer with the older VIA K8T800Pro which supports AGP (Asus
A8V Deluxe)?

I searched the archives for some of these terms and couldn't find anything.

Thanks,
Mark
