Built a machine with i5-2500k and Biostar TZ77A last month. The $50 off 2500k combo no longer works this month unfortunately, so next best thing is another $30 for the ivy bridge part. Anyhow, if your going to overclock on a budget, that Biostar is actually a pretty decent board. 8 phase power + the bios settings for <$100 is hard to beat. If your not going to overclock, I would go with the Gigabyte DS3H board which offers pretty good spec for the money albeit no real overclocking ability. It also happens to be probably THE best board to use for a hackintosh EVER! OSX installs onto a system based on it nearly perfectly without workarounds or hacks. Essentially as good as a native mac. Anyhow, that is a pretty cool plus as well if you have ever thought about toying around with a hackintosh build.
