I, like most pc enthusiasts, am extremely interested in the 5850 and 470. I prefer AMD builds and multi-gpu set-ups. I do tend to lean more towards Nvidia in terms of gpu's. I do, however, love the AMD 890FX chipset because of all of the new features it yields. I don't like that it only supports crossfire; I completely understand it, but I don't like it. So, my question is, has anybody heard of an upcoming Nvidia AM3 SLI chipset that will support 6 gb/s sata and usb 3.0? This will help me decide if I want to go with 5850 or 470 setup.
