However, a GM told me that if he used Scid on a regular basis he might well gain around 25-50 elo points as pre-round preparation will be faster. He said the same about chess assistant though! He was comparing all programs to chessbase.
Scid has less bells and whistles than chessbase. However, it is very fast on searches, trees etc. If someone wants bells and whistles, play a video game instead
That being said, jose-chess.sourceforge.net is a bells and whistles free program similar to the fritz GUI.
