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).

Actually you can get NVidia's top consumer GPU today, the RTX 4090, for $1500-1600. Go back one generation and you can get a RTX 3090 for $750 which still packs a punch.

So it's quite possible to build a well-performing gaming PC for sub-$2000 with RTX 3090 which is still significantly more performant than Apple's latest Mac, in terms of GPU throughput.

I snapped myself a gaming PC for $1300 at last year's Thanksgiving sales, came with a AMD Ryzen, RTX 3080 (10 GB VRAM model) and 32 GB DDR4 RAM, no way I could have gotten a Mac with that performance for anything close in terms of price.
