This is wildly false, see https://www.reddit.com/r/buildapc/comments/143ugg4/comment/j... as a real world example of a gaming PC you can buy right now for $2,600 which is the top of the crop and an absolutely wild gaming machine that's vastly better at gaming than $5,000 M2 Ultra Mac Studio even if the comparisons are done only in games that actually work and work well on the Mac.

If you were after a comparable experience with the fastest Macs on Earth you could configure a PC that's another $1,000 cheaper than that ($1,600).
