Yeah, not a bad price. What's quoted above is parts pricing, not a full build price.
 
You can certainly build it yourself for less, but then you have to build it. If it runs and is what you want... get it.
 
Parts right now are scarce and pricey, even older gens.  It's a sellers market, so you're paying a premium.  As long as you know that... do what ya gotta do.
 

The two main components in this PC is the i7 8086K and the 2080 Super.
So you can compare this PC to buying a completely new PC with similar components:
 
The i5 10600K can replace 8086K (both are 14nm 6C/12T CPU with good ability for overclocking)
The 3060 ti have very similar performance to the 2080 Super. 
 
Using PCPartPicker I have assembled the exact same build to see what it would cost to buy this brand new.

Total cost would be roughly 1700 USD if you bought a new PC with the same performance. 
 
 
 

ah ok , they are looking for a USD price as opposed to a different dollar type. When determining the cost of an item be sure it's the "average cost" vs "the lowest you can find". otherwise you may have conflicting information such as
 
 

it's not too bad for the price considering the 2080 super is 700$ by itself right now

stock cooler is loud but good enough.

5600x is very similar to 3700x. if you can get the 5600x around 300 USD that would be nice. otherwise second hand 3700x or 2700 shoudl be nice.
Also good motherboard for 3700x or 2700 is asrock b450 pro 4  and b550 pro 4 is good for 5600x. for reference.

I suggest you wait for the CPU but my motherboard now as more people will by the motherboards and value will go slightly up

Once unplugged, push the power button a few times first, is my understanding, as this 'flushes' the capacitors on the board, so no build up less chance of shocking the board.
 
Then either set CMOS by jumper or switch, or simply remove the battery for a bit and then replace it.

Chances are the board is fine, it just had a dead CPU in it if anything.
You can try it with one of the others and see what goes to determine if the other chip got knackered.

That's one way... there may be a jumper on the 'board that you can short, as the power's switched on, too

You should also do your own research, never rely on one source. 

The CPU is fine. 

6th gen and 7th gen Intel CPUs work with 100 series and 200 series chipsets. 8th and 9th gen CPUs work with 300 series chipsets.
It's the same numbers of pins, just very slightly different layout iirc. Either way, your 6700 won't work with a 300 series board.
