Hey folks, I'm looking to upgrade my motherboard as I feel like my current B450 setup is holding back my system. Right now, I've got a Gigabyte B450 Aorus Elite V2 paired with a Ryzen 7 5700X3D, but I think it limits my performance significantly. My CPU is cooled with a Fortis 5 + Liquid Metal and I'm able to maintain a pretty stable -30 degrees on all cores using PBO2 Tuner. However, I want a motherboard that can allow me to set this permanently in BIOS. My GPU is an RTX 5070 Ti that's overclocked quite a bit, pulling up to 300W. I have a robust 1200W PSU, so I need a board with solid VRMs to maintain that stability. I plan to stick with DDR4 for now, since I think my CPU is still really powerful and switching to AM5 right now just isn't worth it for me.
Here's what I'm looking for in a new board:
1. PCIe 4.0 support to fully utilize my GPU's potential, since my current B450 restricts me to PCIe 3.0.
2. Dual Fast M.2 slots, as I'm adding another 4TB NVMe drive mostly for gaming and CAD work (like CATIA and Inventor), and I can't afford any lags during heavy loads.
3. I'm also really focused on keeping temperatures low and noise down, aiming for a board with excellent cooling to avoid cranking up my case fans.
So, should I search for a used X570 board to get the dual PCIe 4.0 M.2 capability, or will a high-end B550 board like the MSI Tomahawk give me the thermal performance and stability I need? Thanks a lot!

For your needs, I’d suggest going with the MSI B550 Tomahawk or the ASUS B550 ROG Strix. Both boards check all the boxes you've laid out—great thermal performance and enough features to future-proof your setup.
Honestly, a top-tier B550 board should be more than enough for what you’re looking to do. Unless you’re aiming for something super premium, I’d recommend sticking with B550 models that still have robust features without the higher price tag of X570. If you want the best, ASUS ROG Strix is a great option, but the Aorus from Gigabyte or MSI’s MPG line is also worth considering. Just pick the one that fits your budget best!
My budget is around $150, so I appreciate the advice!
You can actually adjust your PBO settings in BIOS right now; it should be under the AMD Overclocking section. It might take some digging to find, but it's there! As for the PCIe 4.0, while it’s nice, most GPU tasks don’t need it unless you’re really pushing your system with CAD work—make sure to check some benchmarks. You might want to weigh the importance of dual M.2 slots against your budget too. And keep in mind that the VRM mainly manages CPU power, and the GPU has its own VRM. If you do upgrade, just steer clear of any X570 boards with chipset fans to avoid added noise.
I actually spent hours searching for that setting and couldn’t find it! But I know that upgrading to an M.2 will significantly improve my performance compared to using an HDD, especially for storing CAD files. My current setup can hit 50°C, so I’m hoping for a board that provides solid power delivery without overheating.
I was leaning towards the MSI too, looks solid!
