I am selling 2 days old MSI Rx 580 8gb for $330 on eBay if you are looking to get all two together. It runs 30 mhs with Ethereum no problem. I am selling it because I could not find all the cards that I needed to complete my rig.  .     http://www.ebay.com/itm/202045870632?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1558.l2649
