They were $440 before shipping tax on sale in this thread. https://hardforum.com/threads/refurbished-zotac-geforce-gtx-1080-ti-439-99-tax-s-h.1982839/ I bought them in late June and they have 90 day warranties through Zotac. I've not registered them. I bought these for me, thinking I would spin up a second mining rig as BTC price shot up again (towards $13K). Just running six 1070 cards right now in my single mining rig. Profits never took off for mining with the uptick in BTC over the last month --- not enough to outweigh electricity/heat in my situation anyway with .13KWh electricity. So they've been sitting in their box waiting in hopes that mining profits would raise, that hasn't happened, and apparently we won't get that wave of higher mining profits this go round. All I did was test the cards individually for one round of 3dMark stress testing in a x370 Ryzen gaming rig. - only a 20 minute stress loop to make sure they worked. These have not been mined on in my possession, nor overclocked. 2 of them are still completely unopened/sealed. I'll take a small loss, for my own ill-timed gamble on ordering these in hopes of mining profits spinning up, but I'll not lose my shirt - or i'll just keep them till fall I guess when I can use them in my mining setup for winter heat. --------------------- $475 shipped and insured for the 2x unopened refurb units $460 shipped and insured for the 6x opened/shortly tested refurb units These have RGB lighting (color selectably on the Zotac logo) and nice quality dual fans that turn completely off at idle, and the fancy heat plat on the top of the card. Literally less than 1/2 hour of stress test on the open units since they've been in my possession.. Those tested all passed the 3DMark stress test (required 97% stability on FPS).
