Want to buy AMD/ATI Radeon HD5850, 5870, 5970, 6870, 6950,6970, 6990. Will use http://pricewatch.com
to adjust to fair market value. Determine if the card you want to trade can do over 250MH/s https://en.bitcoin.it/wiki/Mining_hardware_comparison
Dead Serious, no cash, just bitcoins. I will mark up the fair market by 10%-15% to help absorb the volatility of the BTC market right now; this post assumes that BTC ~= $27.50 USD or so.
Have a Fry's electronics near you? Then you live near me. We can go together and i can transfer you the BTC in the parking lot, go into the store, buy a 5850 and go our merry ways.
EDIT: an extra 2BTC over market for XFX brand if it is used. Offer does not apply if the card is brand new in box.
