Proxy component, in SketchUp term, is used to replace objects with high-poly counts so that you can avoid the delay to complete the rendering. Saving time in rendering will let you focus on other designing detail of your SketchUp.
You can use both low-poly and high-poly count in Proxy component as per your requirement. Creating models and setting their views will preferably be done with the low poly version. The high-poly count is used for the rendering that maintains the quality of the picture. Current components of your model get the required replacement with this feature. You can use the same name for replacing your current component with low poly and high poly geometry. You can also create a new component with a different name that has high-poly layer in the original form and low poly geometry in low poly layer.
