Hey everyone! I recently upgraded my GPU to a 5090 RTX for my VFX work, which requires a ton of power for handling huge data sets and lots of test renders. I was really happy with my 3090 for most tasks, but since the 5090 is a slimmer card, it’s freed up a PCIe slot. I’m planning to get a riser cable for the 3090, but since it’s my first time using two GPUs, I’m looking for advice on how to make the most out of both cards. I do casual gaming, and I don’t need to do much batch rendering since I usually send large jobs to a render farm. Here are my questions: Should I use the 3090 for my three monitors, or should I spread the monitors across both cards? I have 4 PCIe slots available, and I’m curious if it matters which slot I use for the 3090. Any tips? Thanks!

You might want to consider donating the 3090 if you’re not planning to use it heavily. But if you’re keen on keeping it, you’ll need to make sure you have the right motherboard. To fully utilize the 3090 for computational tasks, ensure it’s running on at least 8 PCIe Gen 4 lanes. Since you have the ROG Zenith II Extreme Alpha, which is solid, you should be good!
For rendering and heavy workloads, you can definitely use the 3090 as a dedicated PhysX card. It helps with physics calculations in certain games, which can give you a slight boost in gaming performance. Just keep in mind how you’re splitting tasks between the two GPUs to maximize efficiency.
That’s a great idea! I didn’t think about using it that way. Thanks for the tip!
