ultrawide Monitor but RTX2070s and Ryzen 1700x

so I spent all my money for a 49“ OLED Monitor and can only buy a new CPU or GPU. .. for max. 400€ .. normally my pc runs games in WQHD and 27“ fine but do you guy think I shoul upgrade or wait and Upgrade in end of 2024 on Intel new socket and a better GPU? Tipps please, thanks! *edit I know that my actual setup CANT run games in Ultra wide mode, hopfully it will after i upgrade my whole setup end 2024 or beginning 2025
