Where did you get a 660 for $100?
I found it on refurb/clearance at a local Micro Center. I've actually picked up TWO of them for that price, it was actually $125 after tax, but the card came with a $25 rebate. The EVGA one I purchased for myself has since died, but RMA has been great to me. The other was an MSI with a Twin Frozer cooler, which is still working great.
