Best Practices For Building A Multiple GPU System

[Tutor]

Congratulation on reaching 10! I’m still keeping my Zs.

So....
Not much has really happened in the world since last post...been pretty boring actually, right?...

Anywayz....My current thoughts on rigs.
3080s are on their way now...
I've taken a different approach to amassing GPUs.
I originally stocked up on Titan Zs, and then migrated over a period to a stock up on Titan X Pascals.
But I do not think I will be doing this anymore. Instead what I'll do is phase them in as I go along.
Add in a single card generationally, and knock off the oldest card in the mix, one at a time.

So when the next Titan comes out, I will get that and move out the GTX Titan I have, which is my "10th"-card, and my rig's oldest.
As I use Unreal and iClone, which are 1-GPU applications, I want to have the best available GPU up top.
And while I would like to have 10 RTX Titans, Octane can't maximize that power to really where it is a cost-advantage vs sitting with the ones you have.

So I guess my thought is if you do get a multi-GPU rig, you could very well start with the 'best' cost-proportionate and get 10 RTX Titans.
But then with the next wave of GPU release, don't feel you need to get 10 more of the newest. Instead just get 1, and set that at top, and just phase them in.

Of course it can be argued that the whole thing of spending $ on multi-GPUs is insane. But we are here talking about multi-GPU rigs, so let insanity reign.
