The GPU, AE's ray tracing engine will take advantage of Cuda Cores on the 680, it will go a lot faster.

[John Cuevas] "You lost me, what is 2GB or 4GB?"

Hi John, the GTX680 has a 2GB and a 4GB model. I'm not certain if AE or even PPro takes advantage of the additional 2GB in the 4GB rendition of the 680.

Yes, the greater amount of VRAM can be quite useful, especially when dealing with very large frames or with environment maps in After Effects.

"The new ray tracing feature becomes truly interactive with NVIDIA® Quadro® GPUs, delivering final frames up to 27x faster than with high-end CPUs alone.¹"

It is there in nVIDIA website:
