Issue beautifully solved by the tech guru smbsmbsmb123

dont listen to the other guy either. a top shelf gpu is utterly unnecessary, most folk get much more oomph from ensuring their pcie buses are free than upgrading their gpus (for this specific task at that level of efficiency).

given your circumstance, however, you should just run these tasks on an ipad. its the cheapest commercial product that is properly optimised for transcoding media, and will run circles around anything your wintel machine could do. even if you were to spend a few months of mortgage payments upgrading it into anything resembling a media editing tool.

also, dont listen to the fool. [en/re]coding heaps of analogue data isnt primarily constrained by computational power. current devices are already plenty capable of dealing with it computationally, hence the iphone having no issue with 8k resolution today.

the other constraints, primarily storage, but no less importantly bandwidth, will in no way benefit from qubits (or whatever other nonsense marketing moniker will be misplastered all over the consumer facing side). its actually extremely likely that all these issues will be exacerbated and constraints amplified by the move.
