I know the difference in performance is around 10%-20% faster for the GTX1080TI according to the [H]ardOCP article I read. I see GTX 1080ti for sale on Ebay (Used) for around $500 plus shipping, give or take $10-15. I can get a RTX2070 for $479 on Newegg with rebate. Which way would you go? (Pairing with a Ryzen 1700 - which will be upgraded to the new Ryzen when it comes out). Currently use a Vega56. Thanks!
