Best PC build for $750?

Hey there.
I'm looking for some help putting together a gaming rig with a budget of $1667.

Before you come crashing in like a malfunctioning parachute, maybe try doing a little reading first. 😵

8. When posting about buying a new PC, you MANDATORILY need to answer these questions:
- What’s your budget looking like?
- Which retailer are you hitting up (paying cash or using a card)?
- What’s the main use case—gaming, work, or just browsing?
- What parts are we talking about? Do you need a monitor, keyboard, mouse, etc.?
- Are you planning on overclocking anything?
- Does aesthetics or noise level matter to you?
- Building it yourself or having a shop like Best Buy put it together?
