I’ve started writing this but somehow got distracted and forgot to hit reply lol.
I’m with some of the others when it comes down to building your own pc. You can end up squeezing a more performance out of your cash. You can start with a decent pre built base build and then upgrade that puppy.
Processor. This boils down to preference. If you prefer intel or AMD. Whatever you choose here will dictate what mother you will get. I have been getting by with a lot of game by running an intel i5 8600k. I’ve always used intel so I wouldn’t be able to recommend an AMD alternative.
Get a motherboard that has nvme M.2 compatibility. @Soju-VB suggested I get a Samsung 970 evo and oh boy was that purchase worth it. By the time I turn on my TV, about 7 seconds, I’m already at the login. Make sure you install your OS on this drive. You could always have 2-3 TB HDD or SSD for additional storage.
Motherboard. Depending on which processor you chose, most companies offer a intel and a AMD version. I recommend Gigabyte Z370 AORUS Gaming. I’ve been using it for a while now with absolutely no issues. (Note if you pick a current gen processor, you need to flash the bios and that can get messy if it goes wrong for any reason)
Graphics card. I currently have a RX 5500 XT and it handles Godfall with ease. If you prefer Nvidia, GTX 1660 is a good alternative.
RAM. I currently have 16gb (4x4gb) and that seems to work for what I need to do. I’d eventually upgrade to 32gb since I’m a believer of have it and not need it then need it and not have it.
Like @majorvex mentioned, a power supply of 600 to 750 to start would pretty much satisfy most power need until you start getting into the flashier rgb stuff. I personally would opt to go with a 650 gold psu and for ease of cable management, a modular one.
If you have a spare TV lying around, I would skip buying a monitor for now and use that towards better components. You can play around in pcpartpicker like @Pugnacious recommended. When I’m trying to check if there is any compatibility issues with the parts I selected, this site is extremely helpful.
You could always say heck it with building and shopping for a pc and just invest in Shadow like @Envyv77 mentioned. I also use this when I’m on the go or when I’m on my old laptop and can run all my games with ease.
Just my 3c.
