Wow awesome thank you!!! I'm gonna look around a bit too just to make sure there's nothing extra I need/want but thats definitely a solid choice and it'll give me some extra room in my budget!

If you are not getting a CPU strictly for gaming, get the same priced AMD chip.  Tiny bit behind in gaming, way ahead in other things... especially on the video side of things.
 
CPU compatibility issues havent been an issue with a new CPU for a decade or more, unless you count first gen Ryzen being kinda picky about memory if going above ~2400 at launch.
 
If you count feature checkboxes, Ryzen is ahead currently as it supports PCIe 4.0.  5GB/s SSD transfers are possible because of this, up from 2.5GB/s.

If you dont need anything extra built into the MB, thats about as good as it gets.  Strong VRM, no frills.

You could see if you can find the scaler board, or a cracked same model monitor on ebay/aliexpress and replace all the non-screen electronics in yours from that unit.

Wired ethernet does not work that way by default.  With minimal QoS, which is pretty universally supported, when both PCs access the network over GbE their speed will be 500mbit.
 
No guesswork, you connect media, IoT, and other low bandwidth devices like printers, tablets, and phones up to one AP and computers or high bandwidth devices to the other.  Because both AP's share the same wired back end network, all devices behave as if they are on the same network.  Think of multiple dumb APs as having multiple hubs connected to the same network.  All devices on one hub/AP share the same bandwidth pool.
 
In an ideal world, your in home server connection will not share any common route that leads to the internet.  That way if one device is doing heavy lifting on the server, you dont crap out the other connections.  This would mean that the AP used for the server connection should be on its own port of your primary switch.  OR, you can connect the server directly to the switch integrated with that AP.  In which case you could bang away at the server and no other connection would ever know about it.
 
I would have to MSPaint some example topologies to really make what I am saying clear I think.

Intel i3/AMD R3, 8gb RAM, GbE, 240GB SSD.
 
This is what you want.

Using a RX 470 on an i7-2600k@stock and its not generally not bottlenecked.  Overclocking the CPU to 4.4ghz helps some, but not a ton.
 
i5 will limit a bit more because of no HT, but should be fine for most games.

RX 570, in the US dont spend more than ~$130.
 
The CPU will be a limiting factor sometimes, but it depends on the game.
 
If the tower only has half height slots, you are boned.

Yes, I am stating that. An unlocked 4-core bottlenecks modern cards. That is a fact. Also, bottlenecking does not equal problems, it equals frame drops, lower GPU utilization, stutters, lower minimal fps, and a bad frame time graph.
 
An i5 9400f is a 6-core, not a 4-core. And that i5 9400f outperforms an i7 6700. And the use cases where games can use more than 4 threads aren't that rare anymore.
Also, the R9 390 isn't that weak. It's hotter and draws more power, but it performs in the RX 570 to RX 590 range depending on the game.
 
And also, not everything is in the average and max framerate, framerate consistency and frame pacing are even more important.

i7-6700k should be a first goal IMHO.

my 1060 holds up pretty decently in 2019 games and if not holding up well is the latest titles on max settings at 1440p to 4k yes the 1660 wont hold up well. don't go by what you hear go by what your experiencing and if you don't feel like your frame rate is enough for the games you are currently playing not the games you want to play in the future then upgrade. then in the future when a game comes out say cyberpunk 2077 and yhe 1660 can't handle it to the standards you want them to then you can look into upgrading. thats the way I evaluate things though. 

I don't know if I'd call those the "best components of its time". If anything they're pretty low-end.

Are you using a web browser while gaming?
How about Discord or a music streaming app?
 
If so, the extra RAM helps.
In a few games it helps regardless, especially with in game hitching/loading.

I've honestly forgotten that steam profiles have a "level" attached to them.

They're largely meaningless, much the same as achievements are (to me, at least.)

It could be invalid output of the shader compiler for some reason, or maybe a timing problem.  I know that some motherboards implement HPET/system timer in non-standard ways, perhaps this is part of it?  Maybe it is a result of variation in timing from oscillators on GPU/MB caused by EMI.

Yep.  It gets even worse as your screen size goes up.  1080p @ 30" is horribly aliased in many cases where 1080p @ 15" on my laptop looks great.
 
Pixel size is important, as is pixel spacing... and both get worse as screen size goes up.

Not to mention that FXAA isnt actual anti-aliasing.  Its just an image space blur effect.

Halos/outlines around text are caused by a sharpening filter on your monitor generally.  If you are using VGA, a bad cable can cause a shadow effect where colors dont line up properly.
 
Visible LOD transitions can be caused by improper mipmapping/filtering.  LOD offset can also cause this.

There are kits specific for the Pi that use 1/4OD (fishtank aerator size) tubing.

Not to mention that it matches or exceeds the V64 if you max out its power limit.

When it comes to FX... YES.
 
FX single core performance is Core 2 Duo/Quad level.
 
Resolution will not go up, that is GPU.  But minimum FPS/hitching will be greatly improved.

Not to mention that it matches or exceeds the V64 if you max out its power limit.

Cheapest upgrade is to get a used i7-3770k and Z77 board.  Uses same memory but gives much better single thread performance for games and low thread count tasks.  Single thread performance will climb by ~50% while 8 thread performance will go up by ~10%.
 
The 3770k can generally hit 4.5ghz as well.
 
Beyond that, R5 2600 will nearly double your "full load" performance.  R5 3600 adds another 15% or so on top of that.

That is something else entirely.

Often times wattage isn't the biggest part, it's quality. A 700w Raidmax unit would work much worse than a 450 watt Corsair CXM.
