nah i really like my mini. but i'm just letting anyone who is curious know that you won't get a first-rate experience with the iGPU, even with extra ram. might be usable, but you'll always be on the edge of overloading your weak iGPU, leading to lags and stutters.
i do have one correction to make - youtube 4k@60 does run on Chrome with the iGPU. a few dropped frames but nothing massive. Scrolling seems smoother too, so if this is your browser, you'll be able to get by. EDIT: forgot to mention i used firefox for previous tests
again, me personally i dont use chrome and i want a smooth experience 100% of the time, so im sticking with the egpu.
