ROG Ally X or Gaming PC

Hi

I’m new to PC Gaming, I mainly game on PS5 and Xbox Series X but want to slowly move away from consoles to PC.

I’m not sure if I should continue with the Ally X or cancel my pre order and start building a gaming pc. On the fence between all in or Ally X.

Any advice would be appreciated including components (if that’s your recommendation).

Thanks

EDIT: I have made my decision to purchase the Ally X and also set myself up for the 5090 release. I’ll probably be selling my Xbox Series X and replacing that with the Gaming PC. Keeping the PlayStation for the exclusives (until they end up on PC more often then I’ll get rid of that too).
