Questions for building PC

[joaovictor]

Hi there!

I am building for the first time a PC, so I would like to ask some questions so I can avoid to make a big mistake building this machine:
Based on my research, this is a good configuration for modeling and rendering, but I still have some doubts.
What do you guys think about this please:

CPU:
-i9 13900k (24 cores)

GPU:
(How better is each one of these options so it would worth to buy a higher version?)
-RTX 4090
-RTX 4080
-RTX 3090
-RTX 3080
-RTX 3070

COOLER:
Any recommendation for a tripple cooler?

RAM:
(What matters more here: Gb or DDR4/5 ?)
-64Gb DDR5
-64Gb DRR4
-32Gb DDR5
-32Gb DDR4
(GSkill, ADATA, Crucial, Corsair)

MOTHER BOARD:
(I have no idea about motherboard, do you think this would work for any configuration?)
-Gigabyte Z 690 Aero D ATX LGA 1700

HD:
(I did read about this Seagate on CGDirector, but I wanted to have 2 HDs: one for the OS, and one for storage. Any recommendation for each one?)
-Seagate FireCuda 530

POWER:
-Corsair RMX Series Platinum RM850X 850W

I am sorry for the extense question, but hopefully I will not waste money and all pieces will work well assembled!

Thank you so much!
Joao

Buy the RTX 4090 if you have the budget, as that's the best 'value' among all 40-series cards.
Go for the RTX 3090 if you can find one at around $800-900 if you need the VRAM.

Next best options would be the RTX 4080 and 3070. Again, kinda depends on how your budget stacks up.

Any recommendation for a tripple cooler?

I didn't understand the question, sorry. If you're asking about a CPU cooler, the Noctua nh-d15 is one of the best ones you can get.

-i9 13900k (24 cores)

Go with Intel only if you're not doing any CPU rendering. The Core i9 runs hot and draws too much power under those kinds of workloads.

(I have no idea about motherboard, do you think this would work for any configuration?)
-Gigabyte Z 690 Aero D ATX LGA 1700

Yep!

HD:
(I did read about this Seagate on CGDirector, but I wanted to have 2 HDs: one for the OS, and one for storage. Any recommendation for each one?)
-Seagate FireCuda 530

An NVMe for OS, a separate NVMe (higher capacity) for active projects, and an HDD for archival storage is our recommended storage setup.

POWER:
-Corsair RMX Series Platinum RM850X 850W

If you want to go with the RTX 4090 and the 13900K, up the wattage to 1000W. Else it's perfectly fine.

Thank you SO much @Jerry James for replying!

I don't know whats VRAM, but I will go for the 4090, thank you!

About the triple cooler I meant something like the attached image.

About the CPU, I would need to do some rendering but 90% of time modeling + realtime texturing like Substance Painter.
Would you recommend other than i9 ?

Thanks for the HD and Power orientation!

Would you recommend any store/company to assemble everything? I have really no experience building pc.

thank you so much again!

Would you recommend other than i9 ?

We usually recommend the i7 13700K for non-rendering, viewport-focused tasks. But if you're doing both, a Ryzen 9 7950X is usually the better path.

Depends on your region, so you'll have to search online but building yourself isn't too hard if you follow a guide. We have several step-by-step guides on CGDirector as well.

Awesome! Thank you so much @Jerry James !!
