Bought a new PC

I got a new pc a few days ago with the following specs:
16 gb ddr5 ram, 1tb ssd storage, ryzen 7 7700, rtx 5060 ti *8gb vram*

Im pretty sure this pc can last me a solid 6-8 years, but I wanted to ask yall if there are steam gift cards which are on a discount or any good free games because, currently, I only have half sword (the demo)and cs2.
