While I'm sure AMD's latest high-core count chips may be giving us new cheaper options, high priced Macs have typically been reasonably priced for their specs.
More recently when the 27" 5K iMacs came out, I looked at the price of a 27" 5K IPS DCI-P3 monitor on Dell... it was only $100 less than the iMac, despite the Mac having a full computer in it, in addition to the display. People still complained that they were expensive.
