[SOLVED] What CPU would be good for 2x RTX 3090 setup?

[Thusko]

My work is building a workstation for me and want's me to pick the parts. They want 2x 3090's. Would a CPU like this work? https://www.amazon.com/gp/product/B07ZTYKLZW/ref=ox_sc_saved_title_2?smid=ATVPDKIKX0DER&psc=1 Or should I get a thread-ripper or wait for Zen 3?? I don't know what to do. Thanks for any help.

What will this system be used for?

 

[Thusko]

Rendering 3D animations and doing process intensive sims in Houdini and C4D. I actually think I want 4x 3080's as it has 14,000 more Cuda cores for less money, but what motherboard CPU setup should I get for that?

 

[Thusko]

Wait apparently 3080's don't support SLI at all?

Only 3090 supports NV Link this time around.

Wait apparently 3080's don't support SLI at all?

Would running the render load on 4 cards not linked be an issue for your work? Do you actually have a need for SLI/NV Link?

 

[Thusko]

Oh my bad. I thought you needed SLI do utilize multiple cards for rendering but you don't. What do you guys think of this setup with 4x 3080's then? https://pcpartpicker.com/list/YtQRjp I think I need at least an 1800 W power supply but they don't have one with price on that site. Thanks

Also I've run into problems with VRAM running out on my 12GB 1080ti. I'm worried about the 10Gb on the 3080. Could I combine a 3090 with it's 24GB with some 3080's ?

no you need 2 3090, it s the right card for you friend. avoid 3080
