Should I upgrade my current PC or build a new one for 350Hz gaming?

I currently have an ASUS TUF RTX 3080 Ti 12GB paired with a Ryzen 7 5800X. I recently bought a 1440p 350Hz monitor, but I can't consistently reach 350 FPS in the competitive games I play, so I'm wondering whether I should upgrade my existing system or build an entirely new PC. A bottleneck calculator reported around 40%, although I'm not sure that result is reliable. I mostly play competitive titles and don't care much about frame generation. I could receive roughly $1,000 off a future GPU purchase, but I would have to wait until January. Another option is upgrading the current AM4 system with a Ryzen 7 5800X3D, which has become available again. Money isn't a major concern, but I'm also worried about missing out while DDR5 prices remain high. My current setup still seems capable, so I'd mainly be upgrading to make better use of the monitor.

If 350 FPS is the actual target, youโ€™d likely need a top-end GPU such as a 5090, depending on the game and settings. Otherwise, the 5800X3D is probably the most sensible upgrade for your current platform and lets you avoid replacing the motherboard and memory.

The right choice depends heavily on the games. In demanding single-player games, a 3080 Ti can still be heavily utilized and a 5800X3D would be a solid drop-in upgrade. For competitive games, though, the CPU may be the limiting factor, particularly in titles such as Counter-Strike 2. Try lowering settings and checking GPU usage before buying a new graphics card.

Donโ€™t put much stock in online bottleneck calculators. A 40% figure doesnโ€™t really tell you what will happen in your specific games. If youโ€™re already well above 120 FPS, the practical benefit of chasing a constant 350 FPS may be fairly small, especially if your frame times are smooth.

Since cost isnโ€™t a concern and you want a long-term system, moving to AM5 makes more sense than investing heavily in an older platform. Just be prepared for the cost of a new motherboard, DDR5 memory, processor, and possibly a graphics card. Waiting for the discounted GPU could also be worthwhile if your current performance is acceptable.
