New C4d/AE PC Build

[TomFS]

Hello

I’d like to get your advice on my build.
Like a lot of people these days, I’m a motion designer that does as much 2d animation as 3d particle simulations as GPU rendering (Octane and Redshift) so a little confused exactly which direction to go with the parts.
I’ve picked the CPU route as it seems to cover most bases but feel multiple GPU’s are necessary.


Would I be better off going with 3x RTX3060ti’s than 1 or 2 of the higher tier GPU’s, certainly my wallet might appreciate it!

My budget is about £ 4-4.5 K

I guess I'll need a better PSU if i have multiple GPU's? Also will i need a bigger case?

Can you see any other issues I’ve certainly missed?

This was a the parts list from the PC Builder but with only one GPU

CPU: AMD Ryzen 9 5950X 3.4GHz 16-Core Processor
CPU Cooler: be quiet! Dark Rock Pro 4
Motherboard: MSI X570 Tomahawk ATX AM4
Memory: 64GB (4 x 16GB) G.Skill Trident Z Neo DDR4-3600 C16
Storage PCIe-SSD: 2 x Sabrent Rocket 2TB NVMe Gen4 M.2 Solid State Drive
Power Supply: EVGA 650 B5, 80 Plus Bronze 650W Power Supply
Case: Corsair Carbide Series 200R ATX Mid Tower Case

Thanks for any help you can provide,

Tom

For 3 GPUs, you'll need to change your motherboard to the Asus WS Ace x570 as that's the only one currently (as far as I know) that supports 3x GPU at x8 pcielanes. Otherwise, you'll severely bottleneck your performance.

You'll need Dual-Slot Blower Style GPUs, such as Asus Turbo or Gigabyte blower Series to make them all fit and not overheat.

You can compare the benchmark scores of 3x 3060Tis with fewer higer-tier GPUs and see how they fare. Rendering speeds scale nearly linear so that should be easy to figure out. You just have to make sure the amount of VRAM per card on lower-tier GPUs is sufficient for what you want to do with them.

Yes, the PSU definitely needs to be stronger for your endaveours, check your required wattage with a PSU calculator, but you should be needing at least 1000W or even more depending on what GPUs you pick.

As long as the case has enough pcie slot at the back (at least 6, for 3x dual-slot cards) it should be fine. Check the slot placement on the motherboard and compare to the slot-blends at the back of the case to be entirely sure it will be able to house 3x gpus.

Thank you Alex for your detailed reply, lots to think about and research.

Looks like 2 x higher tier may make my journey a bit easier!
