If you're a typical silver 3 player of average mmr, don't bother going Gold right now.
If you gain 20 lp per game, you have to win 5 games to get to 100 LP, then win 2 of those to get to silver 2. then you have to win 7 more total to get to silver 1. then you have to win around 8 more to get to Gold 5
That's 22 games in 22 hours. If you don't win every single game, it won't happen.
I just saved you 22 hours of your life.
