Upgrade assistance please

[RobCee]

I believe it is time for me to blow the dust off my wallet and upgrade my system again.

My current setup is as follows:

i7-5820K @ 3.3GHz​

Gigabyte X99-SLI-CF motherboard​

32 GB RAM​

GTX 980 Ti​

Running 2x 2560x1440 monitors​

Problems with this setup:

Intermittent crashing of the graphics, could be age/heat/driver issues with th ecard​

Processor and motherboard are not supported for Win11​

System speeds aren't what they once were​

I thought a 500GB SSD would be sufficient for the OS...​

Usage is gaming, 3d modelling, coding and general office stuff.

Budget is around £3k max

I am thinking decent, but not ridiculous graphics, >64GB RAM and a robust processor, but have no particular thoughts on any of them.
I have no particular desire to mess about with overclocking or pushing things to the bleeding edges.

Please help steer me towards something suitable.

Cheers,
Rob

Thanks @Tetras, that is very helpful.
I am mainly using Fusion360 for the 3D stuff
Don't have many drives as I offload most data to a NAS.
Again, nothing unusual on the PCI-E side either.

Stock levels do all seem to be a bit low at the moment for some reason...
