Of course 16GB, more power is always better.

Better to have too much than not enough

Don't think you can upgrade to 16 if you got the 8GB

Honestly, if you like drawing at higher resolutions, it's useful. I use Krita and it has a memory indicator, 3000x3000 with multiple layers and transparency goes up in RAM usage very quickly (~2-3gb)

why use overpriced underpowered apple or surface stuff?

why use a PAD anyway? why not use a proper PC? for the price of both you get a well equipped PC. 8GB are very very low for anything graphical...

Because you can drag a desktop PC around. I do most of my works outside or on the go.

Curious, but what do you use?

Sorry about the typo but it seems I can’t edit a comment or forgot how. That should have been can’t drag. I do most of my work away from the drawing table because I’m more of an out doors type. I also can’t afford an expensive bulky PC. I know that most like over kill but I don’t have an endless budget. Then again raising deer is a pretty expensive hobby.

No problem with dragging stuff... unless there is something hidden there that a non-native speaker does not know. I have several, Acer Predator Helios for mobile work. An old severly overclocked I7 (roughly 28%) with a vega and a load of drives as storage and media server and backup PC. (backup computer for work and gaming). A Ryzen 9 5950x on a X570 board with a Radeon 6900 and 64 GB and 3 SSDs and a few hard drives. But that is for severe Gaming (Cyberpunk, Mechwarrior, Star Citizen..., and yeah Red Dead 2 too, downloaded it... absurd size you have to download but have not started playing it yet...) and work (CAD, Fluid Dynamics, Simulations and 3D plant engineering on several screens with a large resolution. Also a bit of programming but its mostly bug hunting... for simple full HD very overblown, you dont need that for full HD. I overclocked the CPU but its not really useful it has potential but there was no real meaningful change, so I undervolted and underclocked the components a bit. roughly half of the new system was paid by my employer... so it is not that impressive... on the old rig I felt the limitations not with star citizen but... stellaris... a strategy game that did a ton of calcs per game tick...

Since I cant draw a straight line no idea how drawing art works but if I open hires pics such as pics from above from drones from existing plants or composites from the ground less than 64GB is a hideous pain but these pics have a very high resolution. if you want HD gaming 600 euros gives you a decent machine for HD, you have to lower the details for WQHD but its still possible. dont scrooge on RAM buy quality stuff cheap RAM can give you a really bad time and the diffference in price between noname and quality is so low its not worth the potential hassle (hazzle?). Proper cooling is important so dont buy micro boards and the corresponding tiny cardboard cases. And dont buy apple, if you buy apple you dont own it, apple owns it, and they let you bleed for pretty mediocre performance, and really bad User interface concepts. you cant repair it properly you cant properly expand it. I still use some components from my original about 10 year old machine in the new one. I tested Raytracing with Cyberpunk and a borrowed Nvidea 4080. More graphics Fidelity with raytracing was barely noticible during play and not really worth double price and half performance in my opinion. Add to that the highly questionable NVi attitude towards their customers... nope...

There is this zoo relatively close to me that found a partial solution to that. Just let the deer roam free and have the paying visitors buy their food at the door. Such gentle strength. Kind of took me by surprise to witness it, first hand.

If you’re going to spend the money, just go for it and get the 16 so you don’t have buyers remorse later.

Either way I'm going to have buyers remorse.

I finally found info on the SP9 i5 with someone doing art on it, but it was done only by one person. I found plenty on the SP9 i7. The when I was playing Red Dead Redemption on the Nintendo switch, I decided to see how well the i5 with 8gb could handle games. I saw them playing Red Dead Redemption 2 on the SP9 i5 8gb and the SP9 i7 16gb, and they both handle the game real well. I look that if a 8gb i5 can handle games like that, I should be able to handle the type of drawing programs that I'll be using. However it still up in the air of what system that I finally get. Thanks for your input.

25 or 6 to 4?

When it comes to Windows 7/8/10/11, never substitute for anything less than 16 gigs of RAM minimal in order to make sure that there's enough system resources available for both the OS and "all" the programs to get stuff done (regardless if it's a tablet, laptop, desktop or otherwise).
