Genius3(p90) already scored good results at 25 minutes per game including 1.5-.5 against kasparov. It lost 2-0 against anand but it also beated anaother GM 2-0 It happened against unprepared opponents and kasparov even complained after it that he believed that he was playing Genius2(kasparov later beated genius3(p120) 1.5-.5 when Genius3 used a different opening book but it was only after some preperation from kasparov. I believe that Shredder4 on K6-450 is clearly better than Genius3 on P90 so I expect it to get more than 50% against the top GM's if they are not prepared unless the top GM's play today significantly better than the level they played in 1994 Uri
