Was ready to buy the RTX2070 with 8 gigs GDDR6 because of the Ray Tracing but then I found a better deal on a refurbished GTX1080TI with 11 gigs GDDR5X for basically the same price but without Ray Tracing. I don't know anything about Ray Tracing except that I don't have it and I want to be prepared. Any thoughts? Is Ray Tracing that big of a deal? Thanks in advance.
