Hi, I currently have an i5-7500 and a GTX 1050 with 8GB RAM, and am looking to massively upgrade my GPU. I would like to spend approx £250, and am currently very tempted to purchase a used GTX 1070 for around that price. With the upcoming AMD releases (which could be nice with my FreeSync 144Hz) and possibility of a well-priced GTX 1160, should I buy the 1070 now, or wait for other cards to come out?
