Doubts on Purchases

Hi guys, I’m in doubt and I wish one of you could help me.
So I recently needed to buy a gaming laptop for my work that is more powerful than my desktop, and I was thinking about selling my desktop and since I would like to play SONY exclusives (The Last Of Us, God Of War, Uncharted etc.) I wonder if I should sell my desktop and buy PS5 or keep it and buy PS4 on second hand
Thank you for your help,
Best regards, Dinis Silva

There is no doubt for you at all, you are 100% Sony guy, so sell your desktop and buy PS5!
