[amibroker] Need help with new computer workstation

Hi.  I haven’t posted for a while because I’ve been busy with other projects.   Now I’m coming back to the fold, but…

 

My current workstation doesn’t have enough horsepower for my scans.  Currently they are running between three and four hours.  Way too long.  So I’m going to buy a new ‘puter.  

 

I need some help on this.  The last time I looked at this issue, the sense that I got was:

 

1)       If you could use something like 8Gb of memory, that you probably be big enough to load the AB DB into memory.  

 

2)       But the only way to use 8Gb of memory is to go to a 64Bit OS.  With 32Bit OS, you can only used 2Gb of memory.

 

3)       There is minimal advantage in running AB in a 64 bit OS.

 

4)       If you did go to a 64 bit OS, many drivers and utilities would not run.  This includes data providers like Quotes Plus (my current provider). 

 

From doing a scan of posts in the AB forum, it looks like nothing has changed in the ‘puter/OS realm.    Further, although Vista will run 64bit, reviews indicate that it’s anywhere from 5% to 25% slower than XP.   So that leaves me with a quandary, what do I do?

 

To maximize the speed of AB scans, what is the best current strategy for buying a computer?  Stick with 32Bit OS?   Any way to use more than 2Gb of memory?   Is Intel Core Duo the fastest box currently?   10K rpm SATA drives the best alternative now?   SCSI drives still faster?   Any other suggestions?

 

Thanks in advance for any feedback.

 

Regards,

 

Dan.
