Here's what I would do.

1. Make a copy of both configs
   
2. Open in a text editor such as Atom with a sort lines plugin
   
3. Sort both configs alphabetically
   
4. Optionally: delete all comments and empty lines
   
5. Open in DiffMerge to see differences

I entered the products into nl.hardware.info, which pulls data from different webshops from the Netherlands. Here’s how that looks like https://i.imgur.com/mGTmcOa.png

Yeah I almost forgot that the non-Founders Edition cards would have better cooling for the same price. Unfortunately, they are pretty much – again – the same price.
https://i.imgur.com/KUlB0fg.png (last two rows are lowest price and average price) Is this the same in other countries too, that the not-Founders are not ~€100 cheaper like the MSRP in USD?

I don’t mind paying for premium stuff, since I am looking forward to playing some GPU intensive games; and to playing 1440p 120Hz with a new display soon™; and since VR is a possibility (not my choice).

Yes for overclocking.

Hi, great to see there’s a thread with someone really knowledgeable.
My budget is (max) €1800 for a first-time build, no reused parts, to upgrade from a Mac that can’t even reach 60fps on some midfights with 720p and toaster settings. I’d like to buy it this week, because I’m really getting tired of this.
I look forward to playing all kinds of games, but mostly TF2. Recording/streaming/video editing: yes. Transport to lan party: yes. VR: uh maybe.
I currently have a 1440p 60Hz display, but look forward to upgrading it in a couple of months.
Note: I’m buying in the Netherlands, but PCPartPicker does not support it yet.

What was the b4nny quote again? Always go for the biggest play?

arena_breakwall_b2 with Class Warfare and random crits on. Full 32 player server. Soldiers vs Scouts. I won the round in less than 10 seconds with 2 crit rockets destroying every Scout. The fairest and most balanced round in the history of custom gamemodes.

I made this Discord announcement for my team mates:
