an endgame and an old PC

For some amusement with chess software give this position to your 'engine', White to move it will most likely say something like = +.01. Then make whatever moves it claims are best. In just a few moves the evaluation jumps to +7.22 or +11.55 or  - you get the idea. An old version of Rybka starts out at = 0.00 but not for long!! If anyone has a really fast new engine and a couple minutes to spare I am curious what the evaluation is with better equipment
