I’m kinda with you on some of that
Me laptop I recently got just cause 3 on discount and I really can’t play it cause it just kills me com

;w; i really dislike how they solder all these vid cards

you can build a purpose built tower for around $500 that can push out 90-120 fps if you know what your doing or for around 800+ build a pc that can do that and work well for general purpose tasks

thats the plan! (400$ is the goal instead ;w;) actually i dont know what im doing and afraid of frying a video card like my dad did when i was 14 so im gonna just browse for a prebuilt QwQ'

its a lot cheaper to build your own just watch a few youtube guides to building a pc linustech has some good walkthru's but i would recommend $500 baseline so you have a decent foundation to upgrade if you desire

if No one has showed you before, PCPartsPicker is a really helpful website for putting things together.

Most i3's or i5's are pretty good...I sadly don't know AMD side too well. Google the processor number and "benchmark" of anything you find and make sure the numbers are high (like 6000+ generally does good).

Amazon isn't too bad of a place to get parts sometimes! Other good places to look are Newegg...but the basics are that there's seven parts you need to worry about:
CPU,
Motherboard (determined by CPU)
RAM (Determined by motherboard)
The case (which also determined in size by the form factor of the motherboard)
Graphics Card (determined by case size)
Power Supply (Make sure its high enough wattage to cover everything, form factor based on the case)
Hard Drive

Find something that looks like a decent price, compare the specs, plug it in to PCPartsPicker, and let its compatibility guide help a bit. Also find people who know this stuff, ask them about it too.
Its really daunting at first but I know find it kind of fun...expensive legos that I will rarely put together lmao. (You can probably get something as good as a prebuilt for cheaper by building yourself, but paying for convenience ain't bad either 8D

good luck!!
