A:AnswerNo, RAM can only be up to 16GB on Best Buy and up to 64GB on apple.com. It is confirmed that you can insert up to 128GB of RAM using the manual below. 21.5-inch iMac do NOT have RAM doors.
A RAM door can be found on the back on 5K 27-inch iMacs. To open it, turn off your iMac and wait 10-20 minutes after shut down. Unplug your iMac, and press the little button in the power supply port. This button releases the door open. Open it further if needed. Then push gently down onto the RAM and remove the old RAM sticks. Then insert your new RAM and push down on it gently. Then, close the door. Confirm that is the door is locked on. Plug it back in. If your iMac doesn't turn on, repeat. If it does, login, and click the Apple icon in the corner and click "About this Mac." Finally, check "Memory" and make sure that the correct amount of RAM can be used. If not, repeat.
A:AnswerThe i5 3.7GHZ iMac with the Radeon 580X will play all recent games, but the frame rates will vary depending on the game and resolution factors. Because of the limited air cooling in the iMac, expect it to get VERY hot for extended game play. Build or buy a PC for better graphics and cooling if you are a serious desktop gamer. Otherwise, this iMac does play games quite well for the casual gamer.
A:AnswerYes. I found a DoubleSight 27 in. monitor (on ebay) and it has a tiny bit more resolution than the iMac, but a fantastic match. I simply plugged it in and the display works in extended mode. So, effectively, I have a "monitor" with 10,240 x 2880 resolution. I just LOVE all that screen "real estate".
I also have an ASUS 27" monitor as the second monitor on my HP pc. It would work the same.
A:AnswerThe new iMacs do not have an optical drive. It really isn't needed since you can listen to music and download pretty much anything on-line or through the app store.
A:AnswerRae - It does not have a touchscreen. Personally, I don't like touchscreens on my main platform but that's just me. If that's what you're hunting, this one doesn't offer it.
