This scene was originally choose to be a personal test for arion , but i give it a try on vray RT, there are many aspects that can be improved.
High Resolution
- Look at right up corner , its black, on cpu ver renders ok
- Opacity maps are not supported by gpu, on cpu yes.
- When mix cpu & gpu opacity works
- Result of mix cpu & gpu have more contrast, why? and also have better reflections
- Image of production give a very black render, a bug?
- When i save file (or don`t) and open another max keeps on loading and doesn'l load anythink and shows only the grey background. another bug?
In my case increase speed was like a 4x , but as you can see on the chart when its on mix mode tends to drecrease the speed not dramaticaly.
For last, i did not run a mix network render because a have an ati card. Dont know what could happen there (cool)
If you want Vlado, i can send you the scene files on my ftp.

), i put 64,4 and 64 on gpu, because with 256 i got errors and doesn't render, i made a quick test and with 128 works fine but my pc lags, thanks for the EVGA tip, 
... also I turned on GI.
