New build - cpu thoughts please

[John J Sheridan]

So I currently have an Intel i5-11400F (6-core, 11th Gen) along with 64Gb DDR4 ram with an Asrock Phantom Gaming 4 (Z590) motherboard. It has been fine up to now but it is struggling with my Astrophotography where I might have several 1000 photos to stack.

The re-build will mostly be used for Astrophotography and a bit of light gaming - currently into RDR2.

Budget is max £2k - will be keeping current case, PSU, GeForce 4080 gpu and M.2 ssds so just looking for thoughts on cpu, ram and mobo please.

Thanks

Thanks people for your replies.

Existing cpu is the bottleneck - when I'm running Siril I can see the cpu spiking at over 95% and sometimes the whole system freezes up for a while then carries on again.

Looking at the Intel 265K but worried as people are saying socket 1851 might be Arrow Lake only so no upgrade path for the future. The AMD AM5 socket looks a better bet. The 7950X is around £450 as against the newer 9950X at around £600 so can't see the logic going for the 9950X when it doesn't seem that much better than the outgoing 7950X ?

64Gb ram seems the obvious choice, or possibly 96Gb (2 x 48Gb) ?

I looked at SSD's using PCIe 5.0 but pretty expensive - already have gen 4 SSD's
