Thank you for the info!

But when octane will be compiled for cuda 3.2??

Hello, i'm sorry for my english.
I want to say when in octane can see all 336 cuda cores and not 224!

PS. I have the cuda toolkit 3.2, but in octane show cuda driver version 3.0.

It makes sense to install 4 x gtx460 2 gb on a asus rampage extreme III?
Have I 336 x 4 cudacores in rendering?

Ask you because i don't know if purchase a motherboard with 4 pci-e 16x for the future or not!

Ok, i purchase 2 x 460 2 gb!

Last questions :

1 - If i purchase one gtx460 2gb and one 768mb, is the same thing of 2 x 2gb?

2 - If i purchase one gtx460 2gb and one 480 o 580 1,5 gb in multi gpu, can i use the 2 gb of 460 for rendering and complessive cudacores?

Thanks at all

Ok but gtx580 its too expensive! :o
in multigpu the cudacores ar comulative?

I want say if (2x - gtx460 2gb) its more quickly than (1x - gtx480 1,5gb) or (2x - gtx480) in rendering.
there are benchmark of multi gpu??

And i want say if 470mb of difference its important.
Beacuse i don't know ram ...

Thank you for the reply
I see that post.

I know that memory is not cumulative.
But cudacores of 2 cards add up in the rendering?

In this benchmark the 480 much better than the 460.

And I think that 2 gtx480 is better than ...

Hello everyone
I want to buy Octane, but first I have to upgrade my pc.
I wanted to know if they are better than:

2 x (gtx460 2GB)

or

1 x (480 gtx 1.5 gb) and maybe in the future add another 480.

Sorry for my English
