In steam overlay, and through the game, the chat/text is very blurry.

I recently upgraded my graphics card, and it works great through the game, since my old graphics card could not handle the game very well. Since I updated it, the chat and steam overlay is very blurry. It's the text between the both. The text in the actual game itself is livable, so I can deal with it. But the text in the overlay... my god. I had to stop playing because I got such a bad headache. It could just be how I'm seeing the game, but I don't think it is, because I was playing before I installed the graphics card, I didn't have problems with the text. I have so far, reinstalled the game, changed the resolution, and changed the graphics quality and went through advanced. Nothing has changed.
If I need to provide an image, if others need to see, or to see if it's just me, I will do so.
