Budget graphics card for PC gaming?

I really need a good graphics card to speed up the fps in my games. Games like minecraft run at about 30fps for me (With fastest fps options), some steam games like rocket league lag too much to even play. I need a graphics card under or about £170. To set an example, I hope minecraft to be at about 80fps (or if possible, more)

You can play minecraft and rocket league on max settings at 4k at 120fps with like a £80 gpu lmao

The gtx 950 and 960 are both very good gpus for the price. A gtx960 can play most every games on high setting or better at 1920x1080 and keep 40-50+ fps. The Gtx950 can play everything on medium or higher settings at 1920x1080.

a 950 would be Way more then enough for those 2 games at 1080P.
