[H]ard|OCP has put together a little guide on improving your Fallout 4 experience with the help of modders and the great people at Nexus Mods.  They describe the basics on how to install mods as there are steps you need to follow to ensure your mods successfully apply, whether installed manually or with the Nexus Mod Manager tool.  They explore several mods than greatly increase the size of textures, making them much better looking as well as adding weather and storms to the mix.  As long as you meet the graphics memory requirements which they mention you should not see much performance degradation when using these mods.  Soon Fallout 4 may be meeting or surpassing Skyrim's impressive mod community.

Of course immediately after [H] covered this topic Bethesda released a new patch which enables HBAO+ for all GPUs and extra debris effects specifically for NVIDIA GPUs.

"Fallout 4 has been out for several months and it is possible that you might find the image quality lacking overall. We take some of the most popular and highly downloaded image quality mods and find out how we can improve the environment in Fallout 4. We modify for visual improvements to give you more immersive gameplay."
