I'm getting my wife ready for when I order a new computer, I drop hints a little at a time so that when I'm ready she knew it was coming. Don't want to drop the bomb all at once. Anyway, I'll have the computer built and my question is: Does a SSD really make that much of a difference? I will only put Trainz on it. If so, what size is recommended? I will be spending close to $2000 so if you had that amount to spend what would you put into it? Thanks.
