I have 1 Visiontek 6990 for sale. This card was bought new in September for the purpose of gaming. I never mined on it. Never Oc'd it or anything. Very solid card. Having two of them is way overkill for pretty much every game out atm outside of some of the terrible crossfire profiles/caps AMD puts out (cough Skyrim)
I'm going away to college and ended up selling my gaming rig to my friend minus one of the 6990's in it (had two) and bought a powerhouse laptop instead.
I'm looking for about 500 USD shipped in bitcoins, Dwolla, or Mtgox USD.
I'm willing to use a Escrow service on the donation option to protect myself. Also maybe a well rep'd middle man.
If this interests you in the slightest, shoot me a pm. I can also provide my phone number if you'd like.
