Using the q6600, probably going to OC at least a little (to around or below 3.0), with 4GB RAM on 64 bit Vista for reference.
Here's 3 mobos I saw on Newegg that had great ratings and good prices/features. They all seem to be the same except some port differences, like having some eSata and more audio ports, whatever. I'd rather have a more reliable motherboard than some extra ports, honestly. Also budget? Try to stay around or under $200. Feel free to find other mobos than these, these just seemed like a great choice.
