Thanks everyone for giving valuable advice on my earlier thread about building a CG workstation. I decided for now the best course of action to be a single GPU system.
So this is what I did.
The build was super straightforward, I have never been able to get to a stable system this fast without headache.
So for my CG workstation needs I went with Ryzen 9 7950X instead of 3D, I doubt 3D would have brought tangible benefits and costed more.
The motherboard is Taichi X670E as I have had extremely good experiences with Taichi boards before. Despite this being labeled as E it fit perfectly to Fractal North, I believe Wendell did the similar build, which I copied.
The cooler is the NH-D15 with dual fans included, but I was not able to fit the rear fan to the heatsink due to my choice of RAM, Vengeance sticks are extremely tall. For thermal paste I skipped Noctua and used Arctic MX-6.
Having been playing with various loads, the hardest load I tried being UE5 shader compile, the temps do go to 95, 96C max, so I think this is not too shabby.
I could potentially look for a smaller fan to the rear CPU heatsink, but even at the present the large case intake fan is directly pointed to the CPU heatsink tower, so that already should not be a completely terrible situation, no?
Memory is 32GB x2 Vengeance DDR5 kit that had EXPO label in Amazon listings. Went simply and enabled the EXPO 6000Mhz profile that in BIOS. Has been rock solid so far, completely stable. Never been this easy. I wonder how much benefit there would be to buy faster ram and try to get it stable at 64GB or more capacity.
48GB sticks have not been available in Japan, getting the memory to 96GB is something I really want to do in near future though. Could potentially buy the sticks in Europe.
Lastly as I am based in Japan I was able to get my hands on brand new Palit RTX4090, those were the only cards within “reasonable” prices. Costed around 299,000 yen which is around 2110 USD. Since I need this for work the cost is justifiable, would have never bought otherwise.
The Palit card came with plastic telescopic card support pole that can be screwed to the rear. I was able to put this in place to prevent card sagging further. Unsure if I should slightly straighten the card by gently pushing it a bit more, putting some pressure to the bar, as I am seeing a slight sag, but overall the card seems extremely solid so this doesn’t seem too bad to me. Anyway it won’t bend further now for sure.
The Palit card came with just 3 PCIE power connectors terminating into the one NVidia connector, as this is not the OC edition. I believe the OC edition comes with four.
I used common sense and drew three separate power leads from the power supply I chose (Corsair HX1200) just to make sure there is no overload.
I have my reasons to choose overkill PSU for this build, mainly I might look at building dual GPU system at one point, although obviously not going to happen in this Fractal North and this baby on top slot covers the bottom slot so only way would be to use extension cable of some kind.
