New S754 Mobo Recommendation?

Definitely I'd recommend something like the MSI K8N Neo3-F. It supports Socket 754 and allows you to use PCI Express. And it retails for only about $78 US.

Standard hardware features include Gigabit LAN and 5.1-channel audio, and if you need to upgrade, three standard PCI slots are present as well as one PCI Express x1 slot.

And MSI are one of the best color coded boards in the market. They even label the positive values on the USB headers.

There are also some tips on choosing a motherboard which you can read about here.

If I could add a question to this discussion:

What is the best nforce-4 based Socket 754 motherboard around in terms of overclocking? The Gigabyte GA-K8NE rev1.x that I have doesn't even run 2 512MB sticks of DDR400 RAM at stock speeds (they slow down to DDR333 - if I set them to DDR400, prime95 pukes errors).

I specifically need to overclock my 64-bit Sempron 3100+, and would prefer nforce4 4x over the old nforce 3.

Thanks
