Will my Ryzen 5 2400G hold back my GTX 1050 Ti?

Honestly, you shouldn't see a significant bottleneck with that setup. The 2400G and 1050 Ti pair fairly well for casual gaming, but if you're aiming for better performance in demanding games, an upgrade down the line would help.

Monitoring your performance is key! If your GPU is hitting 100% usage, then it's definitely a GPU bottleneck. Make sure your monitor is connected to the GPU as well.

A heads up: the R5 2400G lacks TPM, which means it doesn't support Windows 11. Windows 10 security updates are ending soon, so you might want to think about upgrading to a Ryzen 3000 or 5000 series CPU so you’re ready for Windows 11.

What games are you playing? If they’re graphically demanding, it might be more of a GPU issue. I’d recommend upgrading your CPU too if your motherboard supports it - something like a Ryzen 5600 would be great without causing major bottlenecks with newer GPUs.

Performance will vary based on what you’re playing. If you’re consistently at 80-90% GPU usage while gaming, you might be hitting a limit there. For anything other than casual games, consider a CPU upgrade for a smoother experience.

Upgrading your CPU is definitely a good idea if you're feeling performance issues. I have a 1050 Ti myself, and it struggled with 1080p gaming. Depending on your budget, you might want to consider upgrading to something like an RX 580 8GB since they’re quite affordable and can handle 1080p gaming well even today, especially for e-sports and older titles.
