Not so sure about this, remember genius 3 on pentium 90 won a game/25 tourney
over strong grandmasters, computers are known to be even stronger at faster time
controls, another factor is that genius was 200 points below top programs. Anand
Lost a blitz match to rebel 10 running on Amd 450. I doubt a 1900 can suceceed
were Super Grandmastes have failed.
