I'll give $2000 for 10 of the 1060s. They are used, who knows how much you BIOS modded and overclocked the hell out of them. I insist on PayPal for buyer protection, and / or escrow from here. PM me.
Do you really expect us to believe that you voluntarily cut them back to 70% power? I think you're lying.
Pretty typical Craigslist buyer.
I remember a few years back selling some 280X. They were going for like $400 each. Some guy contacts me offering $200 CASH. Saying its used and abused and I am very lucky to get $200 CASH.
While at the same time, the guy had ads selling the exact same card for $400 FIRM.
