Question Worth it to go with RTX3080?

[Spinoro]

5-years-old top of the line Broadwell system: makes sense to upgrade to RTX 3080?

My system:

MB: Gigabyte GA-X99P-SLI
CPU: i7-6950X
RAM: 4x16Gb Corsair Vengeance CMK64GX4M4A2666C16 @2666Mhz
GPU: Radeon Pro Duo 8Gb (TDP: 350W)
DISK: Samsung 950 Pro 512 Gb NVMe (PCIe 4x 8.0 GT/s)

Used mainly for 3D modeling (Blender) and some gaming. I'd like to be able to play Cyberpunk 2077 fluidly with it, so I'm thinking of replacing the GPU with an RTX 3080.

Does it make sense, while keeping all the other hardware? Is it going to suffer from major bottlenecks?

Make and model of your PSU and it's age? You could drop in pretty much any RTX 3000 series GPU in the system but you will be limited by your processor. It still doesn't mean you can't game with it, it just means you should drop something lower down the order like an RTX3060Ti.

PSU: Corsair RM1000i 1000W, bought in Sep 2016.

I'm reluctant to go lower down the line of Nvidia cards because of memory: GPU rendering in Blender is limited by the amount of GPU memory, and my current one has 8Gb. If that 3070Ti with 16Gb was confirmed, perhaps it would be the best compromise?
