I am looking to buy a new pc and have two questions. I like running LR and PS simultaneously. How much benefit will I see between the i5 and i7 processors? And does 32 G RAM really improve the performance over 16 G?

For processors of the same speed, you'll see better performance with the additional RAM than you would between the processors.

What was behind my question was that I read years ago that beyond a certain point, the extra RAM does not matter. Any comment on this?

It depends upon the programs running. I'm a musician, running a "virtual organ", with WIN 7-64, and 32GB RAM. The organ will not even load with less than about 28 GB, so yes, size DOES matter! My processors are all i5. i7 allows more "threads" to be followed simultaneously. You'll have to research that one because I don't know how to explain it!

That's true. Several years ago, processors could only utilize a certain amount of RAM. So, anything above that amount wouldn't matter, or be "seen" by the processor. However, modern processors can "see" a lot more RAM than the ones produced years ago. Current i5 processors can access 32Mb of RAM.

I suspect that you meant GigaByte (GB), not Megabit (Mb) or MegaByte (MB).

There are other issues to consider as well. What kind on drive do you use? How large is your cache folder? Do you have enough free space on your operating drive? Is your graphics driver up to date? Are you running in 32 or 64-bit mode?

Here is a link to an article by adobe on this topic.

Yes, I did. Not enough coffee at the time of writing that. It is Gb. Thanks for catching that. I'd hate to mislead anyone.

RAM is king. Add as much as you can afford.

Example: I was attempting to stack 200 RAW images converted to DNGs in Photoshop. Each image was 52 Mb, and it took about 1 hr to render. During the process, my 64 Gb of system RAM was 97% in use, and I still could use other applications.

RAM is King.

Ref i5 vs i7, if they are both quad CPUs they can process 4 cores at a time so similar speed processors may not show much difference, but if you get the newer 8th generation i7 it processes 6 cores so considerably faster in general (although maybe not for specific programs). Also, the cache of an i7 is usually 33% larger, speeding up repetitive actions. Plus the i7 is built for multi-tasking, multi-media so yes I recommend it.

As for RAM the computer benefits up to at least 128 Gb. Using Win 10 would consider 16 Gb the minimum to even operate fully, 32 Gb recommended for doing heavy graphic work, probably 64 gig if using sophisticated video software or plan to in future.

LR likes 6 or more cores - i7 or Xeon - faster cpus, 16 gb ram, fast hard drive (for catalog and previews). PS likes 32 gb ram, quad core i7 and a modest graphics card with enough vram to display the image at your screen's resolution - in other words, if you are using a 5K display, don't buy a card with only 512 mb vram. If you are using dual 4K displays, then get at least 3-4 gb vram.

This company gets it right, and they have some really meaningful benchmarks and system configurations - https://www.pugetsystems.com/recommended/Recommended-Systems-for-Adobe-Lightroom-Classic-CC-141/Hardware-Recommendations

True for LR, but more ram for PS allows you to do more without needing to use the scratch disk, which really slows things down.

Your new PC will only take the amount of RAM the motherboard can manage, I have two PC's one with 8gb of RAM (the allowable max, the other with 16gb RAM (also the max) and I cannot really see any difference in processing speeds when using my editing software.
Crucial has an online RAM tester, there is a US version as well as a UK version, here's thine link:

What software do you use? Do you use mutliple layers when editing?

If you sit there with a stop watch, you will be able to see differences, but what fun is that? Adding more memory and faster processors might sound exciting, but the sweet spot of dollars vs speed is fairly low. I currently have Core i7 in my machines, but Core i5 would have been cheaper, and I would not have noticed a difference. It's the same with memory. I have one machine with 32GB of memory, with 12 - 16GB in the others. Read some articles about the actual benefits of spending more money before you splurge.
