Hi,
Have a look here :
http://www.cpubenchmark.net/high_end_cpus.html
Often seen that i7-920 is outdated, prefer i7-860.
You can google "i7-920 versus i7-860"
An example :

Best regards

Thanks TJ.
Number of bars in DB setting is set to 175,000 which should sit within
my CPU cache as I understand it...? So no benefit to making it
smaller. Also, my code is optimized as much as possible using only
visible bars + 40 more... one particular lopping section of code has
also been programmed as a dll in C++.

I am running AB on a Mac Pro right now. 8GB Ram (ram is not one my
constraints). I am running 2 x quad core Intel Xeon X5365 2.99 Ghz
processors.

have another 4 charts running on another instance of AB to utilise
another core.

range of processors. However, given that I can only utilise one core
per instance of AB (and I want to run as few instances of AB as
possible), should I less concerned with going for more cores and more
concerned with perhaps overclocking the cores I do have...?

Extreme Edition to 4Ghz... I don't know if that would be overkill
given there would be a lot of processing power I couldn't access....?
(although having 12Mb of onboard cache looks attractive since I could
run larger DB's in AB more quickly).
