I would like to buy a new graphics card

I bought Doom back in 2016 and thought I'd deal with GPU later. Haven't been playing video games lately but suddenly I have an urge to play Doom again. I currently have AMD Radeon 6850 and the game runs poorly on it. At this point, I cannot justify saving money for the GPU because I have other financial priorities to attend to, but I would really like to play Doom with a proper GPU. I'm not aiming for state of the art. I figure 200 Euro will suffice for my needs.

I guess you can say this is not a noble cause by any stretch of imagination, but it is what it is. I'd like to buy a new GPU to play Doom.

Thank you.
