A video on best computer part deals when you account for the price of electricity.
Most videos about computers related to budget cover either: The best fps per dollar parts, or the best computer you can buy given a budget.
For this video you would instead target a specific fps@resolution in a specific game@settings, then figure out how hard you can downvolt/underclock different computer parts and how much power each of those consumes. Compair the price difference on the different parts, and account for the cost of electricity for running each of those parts.
Examples:
Dota2 @ 120 fps 1080p
CS:GO 144fps 1440p
GodOfWar 60fps 4k (high)
Perhaps a 3050 can run dota2 at 120fps 1080p and using 100watts to do so. Maybe a 3070 can do the same thing massively down-volted and limited to 80watts. If you play 5 hours a day, every day and electricity is 20cents/kw thats $0.6/month, if you kept the gpu for 2 years you would save $14.6 going with the 3070 so not worth it.
Also how many watts are different CPUs and motherboards (is a mATX b550 significantly less than a atx X570?).
Lets have different usage numbers, what about working on the computer 8hours a day on week days (So what are different low-power mode usages) then gaming 2-3hours on week days and 5hours on weekends.
As a follow on maybe you can account for AC, all watts used by computers in a hot area has to have electricity spent to have that heat removed.
This idea came to me because I bought "The Beast - MonsterLabo" and the passive cooling required extensive down-volting and downclocking of my CPU/GPU. In the end I noticed a drop of $5 a month on my electric bill during the summer. This encouraged me to change my plex from threadripper+gpu to intel i5 with iGPU. Combined with selling my old parts I should break even in 11months.
One outlier I have noticed is that my M1 MacBook pro can play world of warcraft @ 3456-2234 @ 60fps while plugged into its 140watt charger. If you are an avid WoW player and you are willing to play on a MacBook propped up on a ergo laptop stand, even though the MacBook would cost around $1,000 more than a desktop+monitor, I imagine the MacBook uses SIGNIFICANTLY less power than the PC setup.
Is there a world where buying a RazerBlade to use as a desktop is actually a better deal than a desktop because its optimized for power efficiency?
Further thought: Using SSDs in your torrent/plex server instead of spinning rust, assuming you can't spin down your rust how expensive is it to power those HDs for 3+ years (spoiler your electricity better be STUPID expensive for this one)
