If you use Linux Intel GPU's have already made huge leaps. I have heard they are pretty popular with Linux gamers.
Intel Keeps dropping the prices on the cards all while their drivers have made massive and I mean massive upgrades. Just look at reviews on YouTube. Just make sure it is the newest because if it isn't then it is already outdated information.
I would suspect with the next GPU releases from Intel that they will be not only competitive straight up with AMD and Nvidia but some features will outpace them, driver issues fixed, and they will do it all by making significant price to performance margins against them trying to undercut them for market share.
