I got my 3060 for like $325 with 12GB ram and it is quite fast. You should prioritize vram over clockspeed, as any speed gains are lost if you have to tile on the GPU.
There will be a new power supply too. It only counts, that it works without problems using ubuntu.
So there is no advantage in speed with 16GB cards? Assume that raw-files have 50MB. Years before I had problems with “tiling”.
At the moment I am thinking on a card with 8GB and DDR7.
I am using parts of my old pc, but everything which needs to be new will be new.
For sure I will buy a new CPU, but no idea which, probably from AMD, depends on the motherboard, which I choose. I have to think carefully about the features I really need.
You may have your reasons for wanting Nvidia, and then this is not an answer to your question, but I would suggest you also look into recent Intel Arc B-series GPUs. I have only tested B580 12GB and it performs very well. Uses 8-pin power connector and is of modest size. For me the big advantage was that all support (kernel module, OpenCL runtime) is already in standard Debian/Ubuntu distributions. No kernel module compiles (Nvidia), no repository to configure for OpenCL support (ROCm for AMD). Here is a comparison for B-series:
I don’t have tests for Nvidia desktop GPUs beyond 2xxx.
Comparing requires changing one factor at a time, e.g. graphics card, while maintaining everything else strictly the same (CPU, RAM, chipset, storage, kernel, darktable version). My tests are mostly random, with many things changing while I have a chance to test another GPU.
Intel Arc B580 „Battlemage“ unter Linux im Test - ComputerBase
Während sich die Situation unter Windows über die vergangenen zwei Jahre deutlich gebessert hat und zum Release der B580 Kompatibilitäts-Probleme und Abstürze unter Windows kein Showstopper mehr waren, hat sich die Situation unter Linux zwar gebessert, ist aber leider noch weit von „läuft gut“ entfernt.
Short said, the B580 is far away to work fine. Ok this is a gaming test, but why this review shouldn’t count?
FWIW, I set up a computer with a 5090 and Ubuntu 24.04 at work recently and indeed had a bit of struggle with the GPU. It seems to work with the nvidia-driver-570-open (the non-“open” didn’t recognise the card). At least nvidia-smi looks good, we didn’t do any actual work with it so far, so cannot say for sure yet.
Did you experience any problems or strange behavior with Linux. I think you use debian. I would like to use it with Ubuntu 24.04
Does your monitor wake up without any problems? My 2 Asus UHD don’t at the moment, that is why I want to build a new pc. No chance to find the problem.
The Ryzen 7 9700X you mentioned at your site, is the same I want to buy.
