GPU setup

[NVN]

no...my titan at home takes 7.45min for 1 frame.
In my work computer, I have two 780
and it takes just 4 minutes to render
exactly double performance!

Thanks guys for all the info in the topic

I've contacted with my hardware shop
and soon I'll probably make some decisions

Cheers,

Btw

my hardware vendor tells me that GPU series 5 (GTX 570) do not correspond well with GPU series 7 (GTX 780),
and as You know for using octane it's good to have one card that is responsbile for interface, and other cards
for actual rendering.

And another question: Let's say i'll resign from my GTX 570 and buy those 2x GTX 780. One of them I'll need to assign
to be used for system purposes (running windows, software interface... etc), and the other for actual rendering. The
question is: will this first card cores will also be used for rendering, or only the second one?

I mean it would be quite stupid to buy 2x good GPUS letting only one to render and be used for things that I could use something
way weaker and chepaer.

What do You think about it? Can You give me some advice in this manner?

Thanks!
Luke
