2013 iMac i7 with 780m GPU (4GB) and 16GB and 3TB fusion I use this mostly for general crap and like to game on it when I can. Hitman/GTA V, etc. The 2017 iMacs seem to come with i5 chips more often than my current i7, but I doubt I would notice this from a next gen chipset...right?? my i7 is 5/6th gen and the 2017 i5 is 7th gen, I think. I see some 2017s with i5 and the Radeon 575 (another 4GB card), but only 1TB fusion and only 8GB of ram. Obviously I would upgrade the RAM anyway, but is a 1TB fusion vs a 3TB one an issue? I dont have my 3TB one filled at all, I use external drives for media and only internal for apps. Basically...would it be worth the $500-800 upgrade price for selling my 2013 iMac and getting a 2017? Im looking mostly for a lateral upgrade more than a huge step up. It is keeping the GPU as high end as possible that I mostly look for. And, no, I am not spending over $2k just for the better Radeons apple offers.
