This computer is very outdated and overpriced but still marked highly for those who aren't as informed on PC hardware. Stay away. As another poster said, you want at least a 1650 at bare minimum for games like Warzone.

It's rough to find a decent gaming computer at a decent price these days. There's options but they're just not great. Keep in mind when you see the prices on these bundles, you're still going to want to think about mouse/keyboard/monitor/mousepad.

This HP Pavilion is a pretty decent computer. Low on internal storage space so you'll have to buy an external hard drive or install one internally. 8GB of ram is almost intolerable. Upgrading ram is the easiest thing though if you're comfortable spending 10 minutes doing so.

The Dell G5 Gaming is decent and configurable. Pick the bottom spec, get an i3-10100, GTX 1660 Super Upgrade for +$45, Memory upgrade to 16GB, Hard drive upgrade to 128GB M.2 SSD + 1TB SATA HDD. Slightly pushing your budget

For the mouse, the Logitech G203. Reputable brand. High quality. Warranty. Cheap enough.

For a keyboard I'd recommend something like this G.SKILL mechanical keyboard. Cherry MX Red switches, white backlight, TKL (smaller). If you want to save a few bucks just search "TKL mechanical keyboard red switch" on amazon and there's some decent options from China that'll save a few bucks. AUKEY, Red Dragon, DREVO, E-Element products.
