1080p vs 720p Gaming diffrence HD

I`m getting comments about 1080p videos , now youtube supports 1080p but what does it mean for you and me?
Can you see the Gaming diffrence 1080p vs 720p ? You only see the diffrence if I zoom the video

1080P vs 720p Pros and cons :

1080P - better quality , long rendering time , big video size = slow loading ( not all the users have a good internet connection )
720p - good quality , normal rendering time , normal video size , fast loading time
I will uplod 1080p videos but i like 720p - its the best format for me .
Note this video is 1080p
