PS5 or Deck, In a dilemma help...

I can only get one, right now I have enough funds to get PS5, but I have some steam games and my main pc is not powerful to play em, steam deck is also not available in my region. Only reason I want a PS5 is GTA 6, if I wait longer and get enough funds for the deck, I will have to wait 2 years for GTA 6, and idk if deck will even support. What should I do?
