Hey all,

It's been a while..
So I'm looking at building a new system, and I'm a bit out of the loop. So just looking for some guidance and hints from the community.

For context, I currently use the following two systems:
Desktop:
i7-4790k
32GB DDR3
GTX 980 Ti

I use this for a heap of stuff, only about 20% gaming. The main things which are running slow/annoying are:
- Blender work
- Unity
- Any 3D modelling stuff
- Compiling code/apps
- Occasional streaming


Laptop:
i7-10875H
32GB DDR4
GTX 3080

I use this for VR, because my desktop just isn't good enough for it. And I'm in VR quite a bit!
This laptop still struggles to multitask while I'm also in VR. And I can't run my headset at max, probably about 70%

The new system:

What I want to be able to do is have 1 system that can do all of the above, really well. Ideally, if I could run my VR headset at max settings, and also stream at the same time that would be amazing.
I was holding off because of the new hardware releases, and initially I was going to jump for the i9-13900k. But after reading/watching some reviews, it might just be a little overkill for me, I'm not sure.

I'm currently looking at the following:
My basket at OcUK:

Total: £1,128.43 (includes delivery: £10.50)​




Also waiting for the 4090 + ATX 3.0 PSU's to become available, hence not added to basket.

I'm just not sure about the motherboard + RAM really!

Any help or tips would be welcomed, am I on the right path going with the above?

Budget is 4k

How much time do you spend waiting for stuff to complete? If a lot, is the bottleneck certainly the CPU?

It's not so much waiting for things to complete, but rather navigation and rotating/moving objects around, moving the viewpoint etc, is extremely sticky/laggy.

Even just trying to model something to 3D print, is very annoying because of this.

I don't know what causes that, but I had a read of this:

It seemed to think that geometry density, resolution, RAM and VRAM were likely to be the issue. If you have task manager (performance monitor) running alongside the viewport, are you getting high RAM/VRAM usage and low CPU/GPU usage?
