Minimising drawbacks of sharing gpu for viewport and rendering

[super gnu]

So I was all set on a 3 gpu system, with my trusty old 670 for viewport duties.

However I've now realised I just can't fit them all in! So I'm going to have to use either one or both titan x'es for viewport and rendering.

I don't care about viewport slowdown, if I'm rendering I go and do something else.

I do care about eating gpu ram though.

I assume that a gpu doing viewports will have less ram available for rendering ?

So... I guess I could render via back-burner to avoid viewport data being loaded? Or in max, Would it help to switch to bounding box before rendering? Or would I need to restart max to clear gpu ram?

Finally, with two monitors, better both on one gpu, or one on each? I assume I want the two gpus evenly loaded ram wise, or the free one will still be limited by the one with less ram available. Any advice on best-practise most appreciated.

Cheers!

These are the sorts of questions/concerns that I share. Never really sure how much GPU RAM is being used at any particular time by any particular application. We often have other apps open alongside MAX, and pretty much every app makes some use of the GPU these days (like photoshop/afx/chrome). With a good old fashioned CPU and RAM, I know what's what.

Download MSI Afterburner. It's a free GPU monitor and it will tell you all kinds of things about your GPUs like ram usage, voltage, temperatures, speed etc...
