Lag Crashes

I have been experiencing pretty much ever since I purchased this game (last Sunday) heavy lag and then sometimes crashes to desktop. At one point it got so bad that I had 4 crashes in a 2 hour spend. I have uninstalled and reinstalled the game and that seems to help the issue. However, I still occasionally get crashes.
I have experienced these crashes in multiple settings, in town with heavy player traffic, out in the world around mobs, and while loading from one area to another. The crash is always preceded by heavy lag for a few seconds. I originally thought that this might be an issue on my end, b/c my friends that I game with have never had this problem. However, one of my friends share the exact same computer specs.
Since then I have found an article that talks about players having this issue in closed beta 4. I have to find anything since the release though. Here is that link:

My drivers are updated, however, I do run with 2 monitors and in the article is says that this could be an issue but not sure. The real frustrating part is that there seems to be know way of diagnosing the problem, so really I have no where to begin to fix it. Does anyone have any info on this issue. Is it just my system or is this something that a lot of players are experiencing.
