no one can be sure about something like that
it depends on how good is the optimization, how much has the technology improved by then (as most dev would optimize their games for the technology they have right then and for the future upcoming technology), and what kind of game is it (AAA heavy-demanding title? E-sport title? etc)
that GPU is meant for 1080p, playing with higher resolution is not recommended for that GPU as it's not their spec's target so i wouldn't even ask about it...
if your PC live a long life and perform well till it becomes obsolete, probably 3-5 years with the CPU falling behind first since the CPU is only 4c/4t and it's locked too, so no OC path available...
followed by your GPU in about another 2-4 years
(i suppose, but since there's no more lifetime warranty for GPU + every part had their own GPU, u'll be pretty lucky already if ur GPU survive that long without any problem...)
