Best graphics card for vray RT osx maya 2013

[Bertjenkins]

Hi

I'm having pretty slow performance with vray RT on the current project i'm working on. (version below)

I am using a 12 core mac pro 2012, with a radeon HD 5770
Will there be a significant benefit to upgrading to a geforce gtx 680?
Or is there a better card out there for the same price area?
I am using snow leapord. If i use mountain lion will this increase speeds?

thanks

Heya

So the Vray RT GPU only works with Nvidia GPU. So your ATI card start to render fail and then your CPU is rendering. You need GTX 680(4gb) GTX Titan or GTX 780 or other Nvidia GTX based graphic cards.

great thanks -

which is the fastest benchmarked nvidia card?
Are these mac compatible these days? I know the 680 is as there is a mac edition
Also is it ok to use Snow Leapord?

[Dariusz Makowski (Dadal)]

I believe its Nvidia Titan 6gb. Not sure if it will work with Mac.

cool thanks

Anyone out there using this on a mac?
I have heard rumours that it draws too much power...
will i need OSX 10 .8.4?
