Hey everyone! I'm ready to upgrade my 7-year-old gaming PC and I'm looking for some serious advice on how to put together a high-end setup. My goal is to run modern games at max settings and achieve around 60-100 FPS, specifically utilizing my Samsung G9 monitor at its full resolution of 5120x1440 and 120Hz. I'm planning to build it with an ATX motherboard inside a Lian Li O11 case. I'm open to both Intel and AMD for the CPU, and I'm specifically considering getting an RTX 5090 for the GPU. Here's what I currently have:
- **CPU:** AMD Ryzen 5 2400G
- **Motherboard:** Gigabyte B450M DS3H
- **GPU:** Radeon RX 580
- **RAM:** 24GB
I need your recommendations on:
- Motherboard
- CPU
- GPU (looking at RTX 5090)
- RAM
- PSU
I'm not tied to any particular brand; I'm just after the best performance and value possible for a build that can handle my target resolution. Also, I'm not worried about budget since I plan to buy components separately over the next 2-3 years. Thanks in advance for your help!

You have a fantastic monitor, so it's great you're upgrading to match it! For the GPU, definitely aim for the 5090; it’s the best out there for ray tracing. If you want budget options, a 9080 would still be solid for your requirements.
For your CPU, if you're aiming for future-proofing, consider going for a Ryzen 5700X3D or even a 5800X3D if you can find it on the second-hand market. It'll give you a great balance for 4K gaming. Just remember that the GPU is more critical for that resolution, so put more budget towards it.
Don't forget to consider your PSU and RAM! For a setup that powerful, you'll need a beefy power supply, and possibly new RAM to optimize performance. I'd recommend looking at high-performance RAM to match your new CPU and GPU. If budget allows, go for 32GB.
If you're planning on doing ray tracing, you're definitely gonna want a powerful GPU like the RTX 5090! It’s the best choice for handling ultra settings at your target resolution. Just make sure to pair it with a solid CPU, like the Ryzen 7 9950X3D, for the best results.
I totally agree! The RTX 5090 will give you amazing performance, especially with ray tracing. Just keep in mind that you might also need a new PSU to support that beast.
If you want something a bit more budget-friendly, consider the RTX 5080 or the 9070XT. They offer decent performance without breaking the bank, so it really depends on how soon you want to upgrade everything or if you're okay waiting a bit longer!

Yeah, I saw that the 4090 has some impressive benchmarks. But if you can get that 5090, you're gonna enjoy a good performance boost!
