Nvidia Professional Cards

[Dadsgoosen]

Hello everyone!

So I am looking to build a professional workstation and I do not know which of the two I will benefit most from:

1x Nvidia Quadro K6000 + 1x Tesla K20 or K40 (Maximus)

OR

2x Nvidia Quadro K6000 (SLI)

The workstation will primarily be used for 3DS MAX rendering for both stills and animations.

Can anyone help me on this subject?

Thanks in advance

Max doesn't support SLI, but GPU renderers like Vray or Iray can take advantage of multiple GPUs. Remember that the the GPU with the least RAM will dictate the size of scene you can render, so don't buy "dual GPU" cards where the RAM is shared (half each).

So what you are basically saying is that when rendering scenes in 3DS MAX with SLI graphic cards you will not benefit much from that?

[Steve_Curley]

No, I'm saying Max does not (cannot) make use of SLI. Period. You can have 2 cards, but not SLI'd.
What it does on a system which has SLI'd cards I have no idea. It's unsupported, so I doubt many have even tried. It probably sees only the 1st card.

So being completly honest I do not have any knowledge on this subject concerning what will be the fastest.

My end goal is to have a machine that can render as fast as possible with either v-ray or iray. What is your suggestions then?

Looking at something like a Titan Z or the Quadro+Tesla combo?

Sorry - never even looked at such cards as they're well out of my price range (hence using a reasonably good consumer card). I don't know enough about them to offer an opinion.
