I'm unsure what to buy, including the PC, monitor, mouse, headphones, and keyboard.
if you wanna go prebuilt - https://www.amazon.com/dp/B0C2BXMY22 its 1500 and gives you like $400 left after taxes so
I would say start with the pc and budget the other items tbh that you could upgrade down the road
https://www.amazon.com/Acer-Monitor-FreeSync-ZeroFrame-ErgoStand/dp/B0BMS9DBVN/ref=cm_cr_arp_d_product_top?ie=UTF8 - $170 monitor
$70 headset that alot of pros in valorant still use - https://hyperx.com/products/hyperx-cloud-ii?variant=40998813827229
could proabably get a steal on a super light somewhere but they usally cost like $100-$150 USD

AM5, 4070 super build
Comes out to $1440
Way better than a prebuilt
Might be able to find GPU for cheaper on ebay or try to find a deal a microcenter for ram mobo cpu if you want to save money on the pc.
