Yes, for panos with 16 images, even at 21 MPixel or more, your 16 GB RAM and a graphic card like the 690 should be enough - in theory
When APG is using all this RAM and VGA RAM then you should see the file load only at the beginning of your work, and at the end, when you are saving
the finished pano. While you are working on the pano, there shouldn't be more file transfers.
But I'm pretty sure that APG isn't working like this. Because APG is developed to deal with much more than 16 images.
It is not common to programming an application in various ways. It is difficult enough to find a way for one optimal workflow.
So normaly the developer is focused on the most complex and demanding cases.
You can test this by using only a view images for a pano, so that all the image data (uncompressed 24 or 48 bit data) should
stay in the RAM. While editing, if you can see permanent file transfers, APG is working with temp files on your disks.
In this case, an SSD drive is a good thing, because it is very fast for small and frequent file transfers.

Not clear which model you are using at the moment:
There is a Nvidia GTX/GTS 460 (1GB VRAM) or a ATI HD 46XX (from 2010, 4670/4650 512MB - 1GB)
(see http://graphics-cards.findthebest.com/compare/31-43/Nvidia-GeForce-GTX-460-vs-ATI-HD-4600-Series)
Which one exactly are you using ?
Which motherbord, CPU and RAM ?
Benchmark for the new GTX690:

Does APP/APG make any use of more than one GPU? If so is ATI Crossfire better than NVidia's SLI?
As sli allows you to have more GPU ram, it's like having double gpu ram. So we'll use that. SLI or crossfire also double the fillrate and power,
we'll use it also. Now, really, for APG, you don't need such power.

So the GForce GTX690 with 4 GB VRAM will be fine for you.
Please note that this graphic card needed 300 watt power from your PSU.
