Hello
I'm building a modeling/rendering box with multiple GPUs and have some questions about Arnold 6
I'm planning a new computer build and aim to get these four cards:
Thanks for any info.

You can have a mix of RTX cards and use them all.
What you can't do is mix RTX and non-RTX cards. In that case, you won't be able to render on all of them at the same time (just the all the RTXs at the same time).
Arnold will use all the GPUs at full capacity yes. It will also pool the memory if you have NVlink.
However you can only Nvlink 2 cards together at the same time. So your memory is bound by these "islands". The only limitation I can think of using differing RTX GPUs at render time is that the less powerful GPU will likely end up throttling the more powerful one as the work is divided between the GPUs evenly.
Thanks for the suggestion Roja, we've added this and a few more answers to the FAQ.
