I have EVGA GTX 1070. Runs a lot of games at 144hz at 1440p on Ultra. This card is crazy fast. https://www.bestadvisor.com/best-graphics-cards
If you absolutely must have the best, you will have to decide if the 1080 is really worth the extra expense and perhaps go for that. Just remember though that you may pay 30% or more in additional cost for 10-15% of additional performance. Either way, happy gaming is in store for you!
