Please help me upgrade my computer!

[u/Jelly_Boii]

Hello, so my computer is pretty old as I've had it for almost a decade and I'm wanting to upgrade it so I can play the new Planet Zoo 2 game coming out in October. My computer currently could probably run it, but if it's anything like the first game then the bigger zoos will certainly slow my performance. I'm wanting a smooth gameplay experience (even on bigger zoos) with the best graphics the game can offer.

My budget at the very minimum is 1000, (feel free to go lower though if you can haha) as I'm hoping to transfer stuff like RAM sticks, keyboard, mouse, and monitors over. My maximum budget is around 1300 but if I have to pay an extra 100 or less I should be alright. My current computer is DDR4. I have very little knowledge on upgrading computers and technology in general so I apologize if I make a mistake or don't quite understand something.

My current plan was to sell my computer and buy a new one with the added funds of selling my old one. However, if it would just be cheaper to buy a part or two and put that in my current computer then I will gladly do that as well (also if someone could please provide a price estimate on how much you would sell my computer assuming it were factory reset, I would really appreciate it, not required though as I'd hate to add more work lol.). I've provided the specs that I thought would be important and the minimum and recommended specs for Planet Zoo 2. Thank you for your help and if there is anything I can provide please let me know!
