Hello,

I am in the process of building a new Premiere editing machine, and was wondering if Adobes Mercury Playback Engine supports SLI, and if having two Nvidia GTX 680's in SLI would be beneficial.

If not, I would rather go the route of investing in a dual socket LGA 2011 board with either two 6 or 8 core processors, instead of the 6 core 3930k and dual 680gtx's.

My main question, I guess, is does Premiere Pro benefit more from Lower core count, higher frequency, and more CUDA cores, or high core count, lower frequency, and less CUDA cores. Here's my two potential builds

6 Core Intel 3930k, overclocked to 4.5ghz
2 x GTX 680's in SLI
32gb RAM

or

2 x 6 Core 3.3ghz E5-1660's
1 x GTX 680
32gb RAM

Thanks so much!

Hi Matt,

Premiere can only utilize a SINGLE Nvidia card for Mercury Playback.

As for processors, what are you editing? Premiere is very snappy with a single Core i7, but if doing a lot of complex After Effects stuff then a dual-processor machine may be beneficial.

It was good to know that premiere doesn't take advantage of dual nvidia cards.

What about the higher frequency / lower cores against lower frequency / more cores thingy ?

I think this did not come out right...

Premiere pro cs6 can use only one gpu for all the cuda stuff but the other gpu will not just be wasted.... it will be used for stuff such as display scaling , color space conversion etc.

After effects otoh will take advantage of both gpus....

So if you are using premiere pro, i bet you also have after effects on yr machine... so looks like if you can do it, get a sli config. it will be worth it one way or the other..

As for the more cores /less freq against higher freq / less cores, i think you cant really come up with a general rule of thunmb exccept that they benefit from more speed and more cores....there could be some kind of critical balance point but needs proper benchmarking...
