Hey everyone! I just picked up a Samsung Odyssey G9 monitor with a resolution of 5160x1440p at 240Hz and I'm looking to upgrade my old RTX 2060 6GB GPU in my Mini-ITX setup that's been around for 6 years. I'm considering a couple of options:
1. A used RTX 3080 10GB (or possibly the RTX 3080 Ti).
2. A new RTX 5070 Prime 12GB.
From what I've gathered, I might need to upgrade my PSU to handle the RTX 3080, but it seems like I can stick with my current PSU for the RTX 5070 since it's less power-hungry. Is that correct? I'm not super tech-savvy, so I want to make sure I'm getting this right.
I mainly use my PC for architectural visualization with tools like Twinmotion and Rhino, along with some casual gaming. However, I've noticed my FPS doesn't max out at 240 in games; it usually ranges from 80 to 140 FPS. I'd love to upgrade so I can also try playing Cyberpunk without needing ultra settings.
Here's a breakdown of my current build:
- CPU: Intel Core i7-9700K
- GPU: Nvidia RTX 2060 6GB
- SSDs: Two Samsung 970 Evo Plus NVMe PCIe M.2 1TB
- HDD: 2TB WD WD20SPZX-11CRAT0
- RAM: Corsair Vengeance LPX DDR4 3200 C16 (32GB total)
- Motherboard: Asus ROG STRIX Z390-I GAMING
- PSU: SilverStone SST-SX650-G (650W)
Thanks for any advice!

I’d recommend going with the RTX 5070 too! It should handle 1440p pretty well, though you might need to tweak some settings to really hit that 240Hz on your ultrawide. There are compact models available that will fit your Mini-ITX setup.
I think the RTX 5070 is a solid choice, especially if you can get it at or near MSRP. Just double-check that it fits in your case since it's bigger than the RTX 2060. And from what I’ve heard, you shouldn't need a PSU upgrade with that card.
If you're considering performance across applications, the RTX 3080 is a stronger card, but it really depends on what software you’re using. AMD cards can sometimes handle workloads better in certain scenarios, so just make sure you research how they perform in your architectural tools.

Yeah, but if you’re not an AMD fan, stick with Nvidia. I wouldn't want to mess with compatibility issues in CAD programs either!
