Can I build a gaming PC for $800 that reaches 120 FPS?

I'm looking to buy a gaming PC in Wisconsin with a budget of about $800. I'd like to play demanding games such as Garry's Mod with heavy addons, GTA V, Sonic Frontiers, Marvel's Spider-Man, Dragon Ball: Sparking! ZERO, and Cyberpunk 2077. Ideally, I want high settings and at least 120 FPS, though I'm open to 60โ€“90 FPS if 120 isn't realistic. I'm flexible about the case and would consider either building or buying a used system.

At this budget, focus on 1080p rather than 1440p. Check used listings and local computer shops, since an older but well-balanced desktop can offer much better value than a brand-new prebuilt. Waiting for a major sale could also help, but donโ€™t assume a sale will make 120 FPS in every demanding game possible.

MellowCedar42: Would it make sense to keep using a console for now and wait for a major sale before buying the PC?

Cyberpunk at 120 FPS with high settings is beyond what most $800 systems can provide, especially if youโ€™re buying new. Look through local listings for complete desktops with a modern six-core CPU and a graphics card around the RTX 3060 Ti, RTX 4060, RX 6700 XT, or better. Make sure the seller provides the exact parts and lets you test the system.

MellowCedar42: If the price is too limiting, I may stick with my PS5 for now and wait for a better deal.

For $800, a used gaming PC is probably your best option. A new build can handle these games at 1080p, but Cyberpunk at 120 FPS on high settings is not realistic without finding an unusually good local deal. Youโ€™ll likely need to use medium settings, upscaling, or a lower frame-rate target.

MellowCedar42: Iโ€™ve reconsidered and would be happy with around 60โ€“90 FPS if that makes the budget more realistic.
