That motherboard does not use a standard power supply, and it also isn't a standard form factor either. I would only use it with a bus powered, low profile GPU. It's a nice computer, but it's not well suited to fitting a full sized GPU. 

Basically crosshair Hero has 60amp VRM stages and dark hero has 90amp VRM stages. but they are both overkill for any Ryzen cpu really.

Now you're in for it.
 
 

Because any recent CPU is DDR4, so why would be buy more DDR3 when the issue is his CPU 

Will try tomorrow thanks for the help so far

That would be the logic but not in this case 
The 1600af has a worse imc and ipc count 
Not to mention the miserable fpu ( compared to the 3100)

I'll toss my 2 cents into the 1600 af bucket.

in the long run, more cores is better.
for gaming 3100 may have a better clock.

If you're thinking about playing at a higher resolution in the future, wait for the new RTX 30 Series to come out ~end of year.
 
Otherwise, your 1080 ti will hold up nicely.

Because water blocks aren’t free. 
His card is outdated and could be out of warranty assuming it has one.
Still an upgrade in several ways. So if the end user wants those then it’s justified. 

What FPS are you currently getting? I don't think it's worth that price for a used card that old. I'd assume your 1080Ti is still a beast, and you could get a brand new 2080 Super for almost that price, and they're super close to the Ti (no pun intended). I'd recommend just waiting for new cards.

I’d do it. Without a doubt. Especially if you’re using an air cooled system. 

Most would see it that way, yes.
 

Well, if you want more performance per buck you should go with AMD (RX 5700) IF you don't mind having driver issues.
Otherwise, I'd recommend the RTX 2060 or the Super version. Super is quite more efficient and what not. When I looked into the stats, it's kind of even worth the money.

Since most of the mainstream is on console, developers are limited in what they can do. With the new console generation developers will be able go gear their games towards more powerful consoles, therefore making games more graphically demanding. All things considered the 1070 is still a good card, but if the OP is going to use a card for 5 years getting whatever is the most powerful is probably the best in the long run. 

Neither of those components have wireless internet built in, because one is a motherboard with no Wifi and the other is an SSD.
Get a pcie WiFi card if you need WiFi.

A clean install of Windows already removes the partition and/or formats it, so there will be nothing left except a fresh install of Windows. There's no need to manually remove Windows beforehand. You do need to backup your data though.

Bought thousands from them over the last decade, never had a problem with legitimate claims for warranty, little silly to expect a replay so soon, its only been 1 work day since Friday (Tuesday is a public holiday in vic) 
 
Call wednesday and ask, accc is just going to tell you to try to work it out with them before they do anything, you need to gain some sort of complaint number or acknowledgment from pccg before they'll take action, by which stage they'll probably have gien you your money back. Unless you just returned something and changed your mind, then under consumer law they've no reason to give you back store credit. 
 
Most of the time I just use PLE or MSY,  price is usually the best returns have been a bit dodgy in the past. 

What it's like to have a laptop made of plastic?  Costs less and is more common than the more special-order only gaming laptop made of carbon fiber I suppose?  ?
 
Why do you feel the need to add an SSD?  That listing says it comes with a 512 GB NVMe SSD, those are the kind you want anyway.  If that's not enough storage and there's room for another one, sure make it two if you want.

NZXT H200 and Lian Li TU150

either the
ASRock B450M/AC Micro ATX AM4
or the
Gigabyte B450M DS3H WIFI Micro ATX AM4
 
according to PC Partpicker those are your only two mATX choices
 
there are a few more mini ITX boards if you want to go that small

No, your MSI board is ATX. If you are switching to an mATX case, get an mATX board. Otherwise, you're either paying more for an equivalent ITX board, losing out on expandability, or possibly getting worse cooling/VRMs.

Fair enough

Well, you might be right, but we can't know for certain. Battlefield 1 (2016) used to take up about 4GB of VRAM at 4K Ultra, while BF5 (2018) uses close to 6-7GB, for example. I'm not saying 11GB is required, I'm just saying that having it won't hurt, neither now nor in the near future.

Really no reason to swap out the 1080 Ti for a 5700 XT. FPS-wise, they're neck in neck, but with the 1080 Ti you're getting 3GB of extra VRAM, so I'd say changing it for a 5700 XT would be a downgrade.
