I would consider a good monitor as the first big choice.
Look for a wider, larger monitor, with a ips type panel.
Wider gives you more immersive gaming and it allows two web pages side by side.
IPS type panels will have a wider 178/178 viewing angle.
D o not begrudge the price for a great monitor.
It will be with you for several generations of builds.
This gigabyte 34" curved unit looks impressive to me at $400.

For gaming, the graphics card is arguably the most important component.
Budget about 2x the cost of the processor for the graphics card.
A i5-10600K is a great gaming processor @$275 It has 12 threads and will run at a clock of 5.0. Most games depend on the single thread clock.
The value of the i7-10700K and 10900K comes from more threads, 16 and 20 respectively.
But, games rarely use more than 4-6 threads effectively.
Here is a review of the 10600K:

The newly announced ryzen 5000 series are impressive in that regard, but are very hard to buy. If you can find a 5600X@300, I would buy that.
On graphics, by my 2/1 budget metric, look for a $600 graphics card.
Preferably one of the new 3000 series cards like the 3070 if you can find one to buy.
Plan on a ssd for windows and games.
you can put a lot of games on a 1tb m.2 pcie ssd.
Samsung and Intel would be my choices there.
Defer on the HDD unless you will be storing large video files.
You can always add one later.
Buy a case you love. It will be with you for a long time.
I look for a case with good front intake capability. two 140mm or 3 120mm intake fans. That is enough to cool anything.
If all of the front intake is filtered, your parts will stay clean.
The mesh front cases are good for this.
Use a good twin tower air cooler like the noctua NH-D15s.
It is just as efficient as a 240 aio liquid cooler but will cost less, run quieter, be more reliable, and will not ever leak.
Lastly,
MY build process:
Before anything, while waiting for your parts to be delivered, download
and read, cover to cover your case and motherboard manual.
Buy a #2 magnetic tip philips screwdriver.
I find it handy to buy a power switch like this for testing.

1. I assemble the critical parts outside of the case.
That lets me test them for functionality easily.
A wood table or cardboard is fine.
2. Plug in only the necessary parts at first. Ram, cpu, cooler, psu.
Do not force anything. Parts fit only one way.
Attach a monitor to the integrated motherboard adapter if you have one, otherwise to the graphics card.
- If your motherboard does not have a PWR button, momentarily touch the two pwr front panel pins with a flat blade screwdriver.
- Repeatedly hit F2 or DEL, and that should get you into the bios display.
- Boot from a cd or usb stick with memtest86 on it. memtest will exercise your ram and cpu functionality.
- Install windows.
- Install the motherboard cd drivers. Particularly the lan drivers so you can access the internet.
Do not select the easy install option, or you will get a bunch of utilities and trialware that you don't want. Drivers only.
- Connect to the internet and install an antivirus program. Microsoft defender is free, easy, and unobtrusive.
- Install your graphics card and driver if you tested with integrated graphics.
You will need to remove the graphics card later to install your motherboard in the case.
As a tip when screwing the motherboard into the posts, give the screw a small counterclockwise turn until you feel a click.
That lets you know that the screw will engage properly.
Make a note of how the graphics card latches into the pcie slot.
The mechanism will be hidden under the card and may be difficult to work if you have not previously checked how.
- Update windows to currency.
- Only now do I take apart what I need to and install it in the case.
- Now is the time to reinstall your graphics card.
