Looking to finally upgrade from my 2013 27" iMac. I really want the new i7 Mini so I can add my own monitor. I have my eyes on the 43" LG. But what holds me back is the lack of GPU, so I am also open to getting another 27" iMac possibly. The iMac is less exciting to me since it looks exactly the same as my current machine. I don't really do much intense GPU stuff, but I have been thinking about starting a youtube channel soon. Any advice? Could I get away with a Mini? Thanks!
