Dual GPU Motherboard Build Help

Sun Feb 06, 2022 2:17 am

Hi everyone, this is my first post, Im a usual reader of the blog, but couldn't find an answer to my question there.

Main uses: Cinema 4D, Redshift, After Effects. Xparticles

CPU: 10700k or 11700k
Mobo: Unknown
GPU 1: RTX 3070 ti
GPU 2: RTX 3060

I've searched but I cant seem to find a motherboard that runs both GPUs at x16 lane speed. It seems that if I run 1 GPU at x16, then the other runs at x8 or both run at x8. I've read that the difference in speeds are negligible, but I would like to future-proof the mobo as I don't plan on building again anytime soon.

Is there are motherboard that runs 2 GPUs at x16 speeds? If not, what is a good suggestion? I've been looking at:
Gigabyte Vision D
MSI MPG Gaming Carbon Z590
Asus ROG Strix Z590-E
Aorus Gigabyte Z490 Master (I can get this one from a friend for really cheap)
Or any other motherboard is fine, as long as its running dual GPUs at x16 or the highest possible.

Thanks for the help

There aren't 32 lanes of PCIe on those chips. You either get 16 or 20 depending on the generation.
Victory requires no explanation. Defeat allows none.
