Which resolution? 1080p? 1440p?
 
RTX 3060 12GB for 1080p, maybe a 4060.
1440p - RTX 4060 Ti, RTX 3070 Ti

Key chattering is a common issue with mechanical switches, especially Cherry MX clones.
 
There's a simple solution that works most of the time. Take the keycap off, press the switch down, drop a few drops of alcohol in, work the switch out, let the alcohol evaporate/dry, and return the cap. If the issue persists, do it again, if three attempts fail the only solution is replacing the switch.

That's what I thought, thanks

Rapidly triggering the switch; press-release-press-release a few dozen times.

board issue
probably just dirty ram slots though so all you have to do is buy a toothbrush and scrub the shit out of the channels that dont wanna detect

This is how I'd do it. First thing is to ditch most of your requests about needing a strong VRM motherboard, Nvidia GPU, and PCIe Gen 4 as all of those are pretty expensive and realistically not necessary. Dropping down to a 5600X is probably the first thing you need, since for 1080p 144Hz it's fine enough and ~$50 cheaper than a 5700X. Ditching the aftermarket cooler and just using the stock cooler is another thing to help (the stock cooler isn't great, but it's good enough to last you a few months until you can upgrade). The RAM can be swapped to a kit not from Corsair, and since 32GB is almost necessary nowadays, you might as well get that since the price isn't really much different (2x16GB is maybe $10 more, and the 2x16GB kit from TeamGroup is still cheaper than that Corsair kit anyway). For the SSD, just getting a 1-2TB drive makes much more sense than a 500GB drive and a 1TB HDD (I'd personally argue that HDDs only make sense in capacities above 4TB nowadays), especially since some modern games are starting to require an SSD in order to run (Starfield is the first to come to mind, though I know there's a couple others as well). You can get a slightly cheaper PSU without sacrificing quality. The RX 6700 XT is quite a bit faster than the RTX 4060 while being slightly cheaper, so unless you absolutely need CUDA or something along those lines (even CUDA support can usually be fixed with ZLUDA, so even that isn't a reason to go Nvidia if you only use it once in a while), this card makes more sense. 
 
If you're just playing games, this system would actually be slightly faster than the one you linked.

Is the BIOS on the latest version?  Some BIOS versions on DDR5 motherboard greatly improved RAM stability and compatability.

If you do work mainly, get a 5700X or a 5800X, if you game mostly get a 5700X3D or 5800X3D.
All of them are great upgrades.

Your RAm is working at 2400 Mhz Instead of 3200. You are loosing a lot.
 
Yes, way worse.
 
You have to turn on XMP or DOCP in the Bios.
 
Also, make sure you're on the latest Bios version.

Is your RAm 2400 MHz or did you forget to turn on XMP?
Because DDR4 2400 would severely bottleneck any Zen 2 or Zen 3 CPU. If it's 3000, 3200 or such not so much.

Seems XMP is not enabled then.
Should be @ ~1600Mhz

The 7900 GRE is noticeably stronger than the 7800XT. Both aren't huge heaters, so the smaller cooling solutions should be fine as long as the case has decent airflow.

Not in 1440p or 4K, but most certainly in 1080p. It's just such a low resolution. 

Latest Bios?
https://www.asrock.com/mb/AMD/A520M-HVS/#BIOS
 
Resizable BAR enabled in the Bios?
 
RAM running XMP? Dual Channel?

Yes.

Yes.

Got it! Yeah I just left it off for the time being, but I'll start trying to find a good clock for it today. Thanks again for the advice!

You can try turning XMP back on and downclocking the RAM to 3000 or 2933. Having the RAM on stock JEDEC 2133/2400 limits your Ryzen a lot.
