Which 7900 XTX model ?

Hello everyone I wanted to ask about this set and please do not be afraid of criticism about the components, because it can even help: https://www.morele.net/inventory/info/20c4f6a3/ Will it be fun to play in esports /role-playing games (singleplayer) in 2K resolution? (as for the monitor I would also use some advice, because I do not know what to choose, and since Iplay such games as I play it would probably be a good choice to choose 1440p 240Hz, but I would rather not buy OLED, because it is very expensive and I would prefer to spend less on this monitor). I am still thinking about the model of this graphics card 7900 XTX, because I have a dilemma which will be the best - looking at their different prices. And btw l'm from Poland but I think besides numbers, prices are pretty similiar and what I mean is for example Sapphire Nitro+ is most likely the most expensive GPU of Radeon.
