I have fixed the VAST majority of my choppiness issues by simply increasing the page file size on my computer. When I was having problems, my page file was only between 768-1528 MB. I quintupled that across multiple drives and only after playing for many hours (4+) straight will I start to get any choppiness.

A word of warning though: When I originally reallocated my page file off of the system hard drive, I encountered the loss of sync problem. To make sure things would work, I performed the common workaround (hard setting the refresh rate to something between 60-100 Hz; I did 75 Hz) both through dxdiag and the Nvidia setting for the screen size I was playing the game at. After that, I had no video sync problems and the game runs very smoothly now.
