I doubt if Fritz7 can analayze for more than 100 hours. I had one bad experience when I gave Deep Fritz more than 100 hours and there was a problem. I am not sure if the problem was an engine problem or only a display problem If I rememeber correctly Fritz did not display the time and the analysis but it could play when I told it to play. Maybe you can give Fritz7 to analyze a position for more than 100 hours in order to test it(here better hardware is not going to help you to do it faster) Uri
