PC Gaming costs have gone down vs the 90s and early 00s.
In the old days, your CPU & GPU were never fast enough and pretty much every generation, or maybe every 2 or 3 generations, you pretty much had to upgrade if you wanted to play modern stuff at reasonable resolutions.
Now, you buy a $200 CPU and stick it in an $80 mobo, and add $100 or less worth of ra m and a $100 SSD and spend 200-300 on a Video card, and you are more or less "good" for like 3 or 4 or even sometimes 5 years.
Late 90s ... a "good" cpu like a PII 400 was like $800
Today, i7s go for around $300.
Late 90s voodoo, voodoo2, cards were generally under $200, but you also needed a 2D card for like $50, and new generations of cards were coming out every year with huge gains.
Used to cost like $300 for a decent hard drive, another $300 or so for some ram, and you wind up with basic gaming PC hardware above $1000.
"overclocking" is expensive today ...
in the old days, Overclocking was simply squeezing a bit more out of your hardware, while sacrificing the various power, temperature, or stability margins set up by the hardware designers
Nowadays "overclocking" is part of the marketing and there are CPU coolers that cost more than the CPU.... But I dismiss most modern day extreme OCing as being nonsense competition.
