around 50 USD, it's a Gigabyte g31m s2l (from 2008), very stable and full of adjustments for OC, for many years now I'm always buying this kind of MB, I used to buy more expensive MBs some 5-10 years ago, but the time showed me that cheaps mbs are the best choice for me, most of the features they lack I never use anyway, and they will normally last forever (will be useless before they fail to work)
