I'll just replace it with comparable performance parts. What used to cost £500 now costs more like £200 if you are happy with a similar level of performance. Look at the steam deck, and that includes the price of a battery, touchscreen and controller inputs!
I wonder how far we are from onboard graphics being comparable to my now 8 year old GPU...
Edit - just looked it up, Radeon 780M is from last gen Ryzen CPUs, not sure when/if G series processors are coming for 9000s CPUs or not. Looks like it might be comparable to a 1050Ti, so they are getting there and that isn't exactly bad performance.
