I'm trying to find an AMD Socet 939 board which has PCI Express 16x slots, preferably one that can support SLI. Are any of these available yet, as I am having trouble finding one.
Story is that nForce4 and KT890 chipsets are supposed to arrive in the shops this month (mid November ?). They will be PCIe.
My guess (I'm in Europe) that they will be actually in the shops not before February/March. From what I've seen here it takes 2-3 months before you see things on the shelves in shops in volume.
I'm aiming for a S939 + PCIe upgrade mid next year. If there's an urgent need for an upgrade you could also look at S754. I think S939 with AGP doesn't make much sense right now.
Dabs.com have just posted the MSI K8N Neo4 Platinum board on their website, none in stock yet though. Retails for £117. This is MSI's nForce4 Ultra based mobo:
