Rook sacrifice situation

In this situation, I thought the e3 square decided the position and, frankly, the match. I figured that I had doubled rooks on the e-file and a bishop attacking the e3 square that could pin the queen on d2. When I played Rxe3, it began the sequence of moves that I had been anticipating and hoping for; it led to me capturing the queen. However, as I look at the computer analysis of the game, I see that the computer doesn't think that this position is particularly advantageous for Black. The material difference is White's additional rook, bishop, and knight to Black's queen and additional pawn. I think Black is in a good position to either capture White's knight on f3 or attack the second row with his queen and rook. What do you guys think?
