Should I spend the extra $ and get the 4GB version of the GTX 670? Unfortunately an extra $50 is a lot for me right now. If 2GB is enough then I won't bother with the 4GB version.
[edit: Actually I'd love to hear, "the 570 is just as good as the 670 for Adobe apps" because the 570 is about a hundred dollars cheaper. But I'm pretty sure the newer Kepler architecture is better.]
I assume more VRAM = better timeline edting in PremPro ... but I can't find a definite answer.
Is OpenGL affeted by how much VRAM is available? It seems so, as you can adjust your VRAM availability to Photoshop - and the Texture Memory setting in AfterFX under the OpenGL Info section...
But ... is the MPE affected by how much VRAM is available?
The 470 handles everything pretty well but I'm guessing the 1.25GB of VRAM I have now is a limiting factor somewhere along the workflow. Or, as Harm has pointed out, it's more likely the actual memory bandwidth that's the limiting factor. The 470 has a bandwidth of approx 132 (IIRC) whereas the 670 is 192. The 570 falls between at 152.
Thank you guys for any thoughts you can share.
