I recently bought a 27-inch 5k iMac thinking it was the newest 2019 version, but it really was the 2017 version. Should I return it and get the 2019 version? I don't really know much about computers. 2017 iMac ($1,699) 3.5 GHz Intel Core 7th gen i5 - Quad core Radeon Pro 575 2019 iMac ($1,729) 3.0GHz Intel Core 8th gen i5 - 6 core Radeon Pro 570x OR bite the bullet and spend a lil bit more to get 2019 iMac ($1,999) 3.1GHz Intel Core 8th gen i5 - 6 core Radeon Pro 575x I'm a grad student, so I'll primarily be using this for daily usage, writing papers, and playing games (steam, sims). Thanks!
