I just got a 1440p 144hz monitor and I was looking to upgrade my gaming rig. I wasn't sure if I should wait to buy a GPU because black Friday is coming up. I was also stuck on getting the 1070ti for $400, 1080 for $450, or 2070 for $500. I heard that the prices of the 1080ti might go down soon as well. If they did I was looking to pick a 1080ti up. I know GPU prices have fluctuated a lot with bitcoin mining and I'm just trying to pick up a new GPU for the best price. I have a 960 right now so I would like to upgrade soon. Are there any suggestions where a good place to get one would be? I've looked on Ebay but they didn't seem to be legit. I just wish crypto currency would fail and all these stupid crypto miners would stop buying all the GPU's.
