I am not looking to upgrade my cpu right now, i will build a new pc someday. I just want to the get the strongest gpu to pair with my cpu for 1080p gaming, with as little bottleneck. Should i rather buy gtx 1050ti, 1060 6gb?Yes. Percentage will vary greatly depending on the game. You could get the GPU and get a better CPU later, like i5-3570 or i7-3770 if you can find them in the used market for decent price.
Fair point but remember the cpu determines the best FPS you can achieve. The GPU determines at what resolution and game settings you can achieve that FPS at. In cpu heavier games from the last few years it’s likely you won’t see any fps difference between the 2 cards. The 580 will however be better when you are able to upgrade the cpu.I think i am better off buying an rx 580, its only like 20 dollars more expensive, but it gets like 10 more fps performance.
