Can anyone give me an idea how much faster a modern 2017 27”IMac i5 quad core 3.4/8 is as compared to an older generation say 2013 27”IMac i5 quad core 3.2 in real terms ?? This will b a music machine only . You can pick up an older machine for considerably less , update the HD for an SSD , max out the RAM .And yu can’t be far off attaining the same level of excellence for a third of the price . Please people am I wrong ??
