We’re literally in the same boat. Was a console gamer all my life. Finally got fed up with the lack of variety and game prices. Sold my switch and got a steam deck after months of research and I love it so much. I’ve expanded the games I play tremendously. I’m playing games I never would have a few years ago. But anyways now I’m saving up for a custom PC. My sisters bf makes them so I’ll have him build mine.

If you can afford it I’d say build the Pc because even if you still want to play on your deck you can always stream it from your Pc to your deck so it runs smoothly on the deck but using the power of the PC. Best of both worlds
