Hello everyone! I plan on building a pc somewhere mid July. I owned previously a prebuilt I got as a gift in 2018, so this is my first time actually choosing, paying, and building everything myself. And yes, I am aware that its a really bad time to build one but I have money saved up and tomorrow is uncertain.

Im not a complete newbie when it comes to hardware and PC's, I already did a bunch of research on what I want and some things are already pretty much locked in place. My budget is around 2-2,5k Euros, but I can go higher if needed. I need it to (obviously) play games and not worry if the new AAA shiny un-optimised EU5 game will run smoothly, but Im also studying in a technical university, and my uni laptop is kinda really dying. I work a lot in CAD softwares, 3D modeling software, all the adobe garbage, and I run a bunch of simulations, so I need the PC to have components great for productivity. If you know something that is important for productivity and I didnt mention it, please let me know.

For the GPU, I plan on getting Radeon 9070xt either Sapphire pure, nitro+ or hellhound. I really dont like NVIDIA personally and in my eyes the 7900xtx is not worth the small improvement.

For the CPU, the first thing I checked was AMD 7 9850x3d as I heard it was the best gaming CPU, but I also found out thats its quite shitty for productivity. So i found the 9950x3d, which seems to literally a couple of % slower in games, but is an absolute monster for productivity. It is quite a bit more expensive but I would like for the PC to last for a long long time, with maybe a GPU upgrade in a couple of years. So if one of you can confirm that the 9950x3d is actually a lot quicker in stuff outisde of gaming, and will be able to last for a very long time, I will pull the trigger.

I did already buy ddr5 32gb of RAM, as I knew I want an am5 socket and it was on a very decent discount. Here im wondering about actually getting a second pair for a total of 64gb? Afaik 32 is more than enough for gaming, but as I mentioned before I want this to be a powerhouse for productivity and I like to multitask on my PC, so if you could let md know if another 32gb would make a big difference, I would appreciate.

This is kind of where my knowledge ends? I now need to find a mother board that would work, a case that would allow for masive ammounts of airflow, as low temperatures are something I extremely care about and im willing to overpay a lot for additional fans so they can run on lower speeds and keep the noise down. I will try to get a good nvme 2tb drive but im willing to get only 1tb now as I have an external 2tb SSD I put my games on rn and just transfer them to my laptops main drive when I want to play. A really good power supply I obviously need as well. Its quite a lot of stuff I need advice on but choosing the GPU and CPU was already so overwhelming, so if anyone can recommend me some good remaining components I would greatly appreciate it! Thanks in advance!

TL;DR - I need help with finding a good Power supply, motherboard, case, a lot of cooling fans and nvme ssd to match the Radeon 9070xt and 9 9950x3d.
