Dean, to give you some idea of the differences between computers I have recorded the following data. I run huge optimizations using AB with Fred's excellent IO optimizer. 2500 stocks, 10 variables, 2 years of EOD data. All systems have 1 Gb of RAM. Times are for 1 full, 36 steps, run thru the optimizer.
Old Dell 2.5 GHz P4, 14 minutes
Dell 3.2 GHz P4 ht, 11 mimutes, ~ equal to processor speed difference
Dell 3.6 GHz P4 ht, 7m 15 sec, noticably quicker than the 3.2 GHz machine.
and last weekend on a friends new Athlon machine
Athlon 3500+, 4m 25 sec, Quick, but expensive to buy in assembled form.
Cheers
Sid

Good excuse to put together a new system. I was thinking of the newer
AMD / Athlon 64 bit systems and was curious whether anyone has had any
positive or negative experiences with newer 64 bit m/boards or chips or
any other thoughts recomendations.
Regards to all..
