I am selling 6 Gigabyte Radeon R9 290X 4 GB cards & 4 Sapphire Tri-X R9 290X 4 GB cards. If you are folding or if you plan to mine Ethereum, these will be great for you. Or if you are looking for a great gaming card, this is the one.

$300 each or best offer. You will save some money buying these used. They hash great. They only mined about 3 months total. Most were NOT running 24/7 or overclocked while mining. They are still in great shape.
