user2042: In order to resurrect an old line in the Scandinavian defense I am forced to accept doubled pawns at the side where I have pawn majority. To make things even worse, I reach queenless middlegame, and the endgame is not so far away! Still, my engine gives equality or small disadvantage in sample lines. 
I don't have hardware strong enough for this type of analysis, so I ask for deep analysis of the following position:
[Title "White to move"]
[fen "rn2kb1r/ppp2ppp/8/5p2/3PN3/8/PPP2PPP/R1B2RK1 w kq - 0 1"]

I really believe that Black might be able to hold this position with equal chances, but I need strong engine analyzing on strong hardware. If required, break the analysis into sub-variations and post them one by one. You could start with 1.Ng5 as I consider it the strongest move. Move 1.Nc5 can be discarded as I intend to play 1...Bxc5 doubling the pawns, thus removing only advantage White has in this position.
I can wait, there is no need to hurry as I prefer quality over speed ( this should be the part of my opening repertoire ).
Thank you for your time and efforts.

<p>There are some differences, but they agree with the fact, that Nc5 is the worst reply.</p>

<p>Here is a game played by Stockfish vs itself in a 40 minutes per 40 moves time control in this position on a Core i7-3770: (the {0.42/27 41} in the PGN denote evaluation, depth and time for the move)</p>
