Alright, so I would like to be a gamer using my mac. I heard that having a GTX 1070 or 1080 is good for gaming, so is there any way I can put it in my mac? Thanks.
iMac (21.5-inch, Late 2015), macOS Sierra (10.12.3), 16 GB of Ram
No.
An iMac has never been design for any significant upgradeability by the user.
There are really no user serviceable/upgradeable in any iMac model.
An iMac typically has ALL of its components soldered/intergrated into the main Logic board.
Sorry.
In addition, finding Mac drivers for such a card would, also, prove equally difficult to find/obtain, for running the Mac OS.
No. Your graphics card is integrated into the logic (mother) board, and it cannot be upgraded, and there is no space for a dedicated card.
Can I put in a GTX 1070 in a iMac?
