Fritz 5.32 smokes this position, finding Nxg5 after 1 second on a PII 400.
Apparently better than Fritz 6a from another post here:

Analysis by Fritz 5.32:

³  (-0.50) 1.Bxg5   00:00:00
=  (-0.09) 1.Nxg5   00:00:00
²  (0.50) 1.Bg3   00:00:00
²  (0.41) 1.Bg3 d6   00:00:00
²  (0.44) 1.Bg3 d6 2.Qd2   00:00:00
²  (0.34) 1.Bg3 d6 2.Qd2 Bb7   00:00:00
²  (0.34) 1.Bg3 d6 2.Qd2 Bg4 3.Qe3   00:00:00
²  (0.31) 1.Bg3 d6 2.Qe2 Nh5 3.d4 Nxg3 4.fxg3   00:00:00
=  (0.22) 1.Bg3 d6 2.Qd2 Bg4 3.Qe3 Ra8 4.Rxa8 Qxa8   00:00:00
²  (0.28) 1.Bg3 d6 2.Re1 Rb6 3.Nd2 Ra6 4.Rxa6 Bxa6 5.Qf3   00:00:01
²  (0.31) 1.Nxg5   00:00:01
²  (0.41) 1.Nxg5 hxg5 2.Bxg5 Qe7 3.f4 exf4 4.Bxf4 Rb7   00:00:02
²  (0.53) 1.Nxg5 hxg5 2.Bxg5 Qe7 3.f4 exf4 4.Bxf4 Qc5+ 5.d4 Qxc3   00:00:03
²  (0.63) 1.Nxg5 hxg5 2.Bxg5 Qe7 3.f4 exf4 4.Bxf4 Qc5+ 5.d4 Qxc3   00:00:07
±  (0.94) 1.Nxg5   00:00:23
±  (1.34) 1.Nxg5 hxg5 2.Bxg5 Qe7 3.f4 exf4 4.d4 Qxe4 5.Bxf6 Qf5   00:00:36
+-  (1.56) 1.Nxg5 hxg5 2.Bxg5 Qe7 3.f4 exf4 4.d4 Qxe4 5.Bxf6 Qf5   00:01:25

Nxg5 absolutely wins, e.g. 1. Nxg5 hxg5 2. Bxg5 Qe7 3. f4 exf4 4. d4 Qxe4
5. Bxf6 Qf5 6. g3 Qxf6 7. Rxf4 Qh6 8. Rg4+ Kh8 9. Rh4 etc.
