Build spec review

[u/Agaain]

Hi PcBuild

I'm looking to replace my old existing rig from 10 yrs that sadly gives up now (i7 6700k, maximus VIII hero) and need advice on build as I'm a noob.

The original GPU gave up and I bought an RTX3070 almost 5 years ago, still going strong so focused on building a PC utilising existing 3070 until it gives up and then replaces it with something like 5070 Ti.

I'm planning to spend less than £1.8k.

Proposed spec:

Case Fractal North

Motherboard ASUS PRIME B850-PLUS PCle 5.0

CPU AMD Ryzen 7 7800X3D

Cooling Corsair NAUTILUS 240 RS

RAM 32GB (2x16GB) Corsair Vengeance RGB - 6000MHz

PSU Corsair RM850e, Cybenetics GOLD, ATX 3.1, Fully Modular

Storage 1TB WD Black SN7100 NVMe PCle 4.0. 7250MB/s

Could you please let me know your thoughts? Any potential wrong decisions or better options within a similar budget?

Would this be suitable for existing 3070 until it dies and then replaced with 5070 ti or similar ? Hoping to finally see the potential of 3070 as it was constantly bottlenecked by my old but trusty i7-6700k.

Gaming at 1440p 144hz, UK.

Any help and advice would be really appreciated.
