Given a system with 64bit Windows 7 and 64 bit PD9,
In your experience, is there a memory ceiling?
If Windows was maxed out (192G) would Win7 offer it to PD9, and would PD9 use it?
Will it place it's temp or shadow files in memory?
Rephrased, What's the practical ceiling for system memory?
Is GPU memory important (size, discreet etc.) for video? (not graphics, not gaming, not 3D)
With a tight budget, would you lean toward system memory or GPU (discreet) memory?
In your experience, is there a memory ceiling?
Yes, what your MB can handle
If Windows was maxed out (192G) would Win7 offer it to PD9,
Yes if 64bit Win7 as you stated and would PD9 use it?
NO, not for the typical timeline editing complexity most users would have. You only need enough memory to handle your timeline, additional tons more memory not utilized.
Will it place it's temp or shadow files in memory?
No, on a high end system one would typically turn shadow files off anyhow
Rephrased, What's the practical ceiling for system memory?
Make sure PD has ~4-6GB available to it for most typical timelines. So depending on what other stuff you have running on the box, 8GB of physical memory could be adequate. If you plan very complex timelines with full HD in all 100 tracks, or if you have lots of memory resident utilities using significant amount of memory, you will have trouble with 8GB physical.
Is GPU memory important (size, discreet etc.) for video? (not graphics, not gaming, not 3D)
On a high end card, 1GB or 2GB is not the game changer for PD, GPU memory not as important as GPU cores, more stream cores and higher core clock speed, much better performance
With a tight budget, would you lean toward system memory or GPU (discreet) memory?
The memory question here to me is a poor question. I think your question is intended to maybe ask CPU or GPU benefits for a tight budget. That really depends on what format your input is and what format you desire for output. GPU and CPU encoding may not be the same quality so it depends on your eye too.
