New PP 14.5 (Build 51) Machine Recommendation

I currently have the Alienware 17 R5

i7 8750H 6 cores

Nvidia 1070 (also has a Internal GPU as well)

32 DDR4 Ram

1TB SSD

With this I have trouble editing the New Sony A7SIII 4k 4:2:2 10bit GOP Long Codecs (S & HS).  It is too glitchy and not worth trying.  Even with proxies it has issues.  Prior to the update my specs were fine for all other 4K files even the 4K 4:2:2 10bit 120fps from Z-cam.  The Prores RAW from Atomos Ninja V I can now edit after updating and tweaking my nVidia settings but start to get problems when playing more than 2 tracks with RAW clips simultaneously.  But still not able to edit the A7SIII files at all.

My question is what specs should I be looking for to crush through these files with this new update that is more resource hungry.  I dont want to spend more money than I have to and buy something that I don't need.

Would a i7 10th gen with RTX 2070 be fine or should I go up to i9?

Also with the new update to PP it crashes a lot.
