i5 8400 or Ryzen 7 2700 is there any discernible difference between these two processors for use with lightwave, both computer come with gtx1060 6gb graphics card.
I've spent hours looking at benchmark tests and understand they are both good for gaming but no wiser as to which would perform best on Lightwave, Painter, Rhino and 3d Coat or whether they would be very similar.
Or an i7 and add fast GTX 1060 card at later date ?.

The i5 8400 is an entry level 8gen CPU. It has good performance compared to previous CPUs thanks to 6 physical cores but no hyperthreading / virtual cores (6 threads compared to 12 in the i7). The Ryzen 2700 (or a an i7) is way faster and the better choice in my opinion.

Personally I prefer spending a bit more money but get better / higher quality components (CPU, motherboard, cooler, PSU, SSD and RAM) that lasts me longer and allows me to render for days at 100% CPU and 4.2+ GHZ on all Cores for days without issues. I always max out memory (64GB currently) right from start so I don't run into RAM compatibility issues later when need the memory.

It depends what system you use now, but I wouldn't get an i5 for content creation. It works of course but the i7 or Ryzen would give you better performance.

The 1060 GPU is ok for LW but too slow to do any serious GPU rendering with it. But definitely enough for modeling / animating.

To best compare rendering / content creation performance, a good indicator is Cinebench R15. Google that up for these CPUs and you will see the big difference (multicore results). Download Cinebench and run it on your current computer to see the what you can expect from upgrading.

Recently acquired new PC with Xeon E5 and compared it with my 7yrs! Old rig with i7, the speed difference is maybe 5%.

You mentioned (Substance?) Painter, to properly use it, you will need a CUDA card like the GF1060 or higher. 3D-Coat when used for texturing will also profit for it.

My conclusion: Get the Ryzen system with the 1060 at least or you will be thinking about upgrading soon again. And maybe the system without a proper GPU doesn't come with a PSU sufficient enough if it is a prebuilt machine.

And as I mentioned before, get as much RAM as possible right from start. If you work with displacements or landscape software for example, 32GB or more might be required.

At the end it depends all on what you want to do with your system.

I meant Corel Painter not Substance Painter, sorry for misunderstanding. Ryzen seems to be the way to go but I will investigate a few other graphics cards. Thankyou.

My current machine is 7-8 year old AMD 8 with 2G nvidia card, anything would be a vast improvement.

Found a pc R 2700 with Wraith cooler, it can run at 4.1 Ghz which looks fast. If it's overclocked will the cpu last as long or would it need replacing after a while ?.

I have an 1800X and a 1700 bought at release, both overclocked to the max I can with water-cooling, both run and render almost 24/7 with flawless performance. Will the CPU's last eight years under this abuse or only four?

Don't care. :)

Would overclocking damage any other components, I would be happy replacing the CPU sometimes.

In the old days, overclocking was a roll of the dice... I first overclocked a dual Pentium 600 to about 800 speed, if memory serves, and it was much more of a challenge than the later Intel and AMD's I've done. Never had any component damaged, other than a single USB port that failed after an aggressive overclocking attempt on an Intel box a few years ago.

Today, it's sort of expected. There are utilities that help you get where you want to go without going too far. I'll let others address all the in's and out's from a tech point of view, as overclocking is not just messing with one setting and with only one place damage can happen, but it's so "controlled" at this point I doubt you're risking anything with the fantastic new 2700 and the current crop of motherboards.

I could have a go at overclocking the AMD 8 and the children AMD 10, nothing to loose as I'm buying a new pc anyway.

Thankyou all for your advice. I bought a Ryzen 7 2700 and Nvidia GTX1060 6gb, only using 8ram at the moment but expect to upgrade that soon. Lightwave, 3Dcoat and Corel Painter all running very well.

good choice   :)

3DCoat will welcome more Ram when that time comes. Happy Rendering!    https://i.imgur.com/w7295Cw.gif
