Hi, Today I have a pretty old iMac - the 21' 2011 model. Although I've upgraded the ram (to 20GB) and the hard-drive to 1TB SSD, I think that its time to upgrade the entire computer. I'd like to purchase an iMac for development, especially for game dev with VR support, so the new iMacs came exactly in time. However, I wonder if the 21' (top customizing options) will be satisfying for VR development? When searching this topic it seems like the 21' won't be able to do VR work, and even the 27' will be in the lower specs that HTC Vive or Oculus requires. The money is not an issue, since I'm buying a computer for the long run, however I do want to get a computer that'll be able to survive at least few years. In addition, the 27' display is too big for me and therefore I'd like to get the 21'.. So my question is - is the following iMac specs will be satisfying for VR gaming & game dev? Thanks in advance!
