I do not disagree, but my post was about the increase in playing strength from a
dual system. Maybe it was directed more at those who think that they are going
to crush everybody on the chess servers with an expensive dual system. :)
However I do agree that there are other nice things you can do with a dual. It's
just that people should know exactly how much stronger it is, and it is not much
stronger.

Well your experience seems to confirm my figures.

If you are limited to 4 pieces TBs, then it's not an improvement at all!
Of course 5-men TBs are going to produce much more TBs hits, and much more work
for the hardisk. And of course the gain you can expect from TBs is going down
for a dual system.

I disagree. 733*1.7=1.246GHz. There are AMD processors running faster than
1.3GHz, so your dual 733MHz is already worse than a fast single processor AMD.

Next Monday Gambit Tiger 2.0 will find its way to your dual. :)
