Where should I connect my monitor?

Hi,
I am wondering if I can plug my 2 monitors using the Intel® UHD Graphics 770 from the i9 12900K and the HDMI and display port on the motherboard, To keep the RTX card for GPU rendering and calculations?

I will be using my computer to do Compositing in After effects, Video editing in Resolve 3D modeling in Blender and GPU rendering in Cycles and Redshift.

Those are the parts of my new PC:
CPU: Intel Core i9 12900K 3.2GHz 16-Core Processor
Motherboard: ASUS ROG Strix Z690-A Gaming WiFi D4
GPU: GeForce RTX™ 3080 Ti GAMING OC 12G
Monitor 1 32 in : DELL3007WFPHC (2560x1600)
Monitor 2 27 in : DELL UP2516 (2560x1440)

Memory: 128GB (4 x 32GB) G.Skill Trident Z Neo DDR4-3600 C16
Storage PCIe-SSD: WD Black SN850 2TB NVMe M.2 Solid State Drive
Power Supply: Corsair RMx Series RM8500x
Case: Fractal Design Define 7 Black ATX Mid Tower Case

Thanks,

It'll work, but it probably won't be offloading too much work off your GPU for it to be worth the hassle, especially when you want to do active work and will need to set a GPU to handle viewport. Powering a display is different from render calculations, and that task alone won't put much of a dent in performance if that's a concern.

@Alex Glawion probably has more insight

Hi Jerry,
Thanks for the fast answer. What do you mean by active work ? Do you mean that, let's say the Blender viewport will slow down with the UHD Graphics 770 from the i9 12900K?

Also my 32 inch monitor only output (2560x1600) to DVI-DL. I bought an active adapter to display port, and it works, but there are some glitches showing on the screen. I am wondering if I could plug my GTX1080 on the PCIe 3.0 x16 slot (x4) of my mother board with the RTX 3080 Ti on the PCIe 5.0 x16 (x16). And connect my monitors on the GTX.

Oh I thought I replied to you, but apparently didn't hit the post button (sheesh). My apologies!

But basically yes. If you're using UHD to drive a display, there are many tasks that you can't offload to a GPU unless that application has created a way for you to do so.

Yep, that should work just fine

Ok. I will try this setup.

Thanks!
