I will get to purchase a new computer and have about $3500.  Ijust wanted
some advice on a couple options.  Ideally I would want something that would
be optimal for things such as Bioconductor and Genespring.

 

In general, I will probably get a system with 4G of RAM and will probably
use the 32 bit Windows XP Pro OS.

 

Most computer purchases here are through Dell, but I may be able to go
through HP if I wanted to get an AMD.

 

Would there be a tremendous amount of difference in computing power for
things like Bioconductor and Genespring between, say 

 

Dual core Xeon (2.8 GHz)

Dual processor Opteron 248  (2.2 GHz)

Pentium Extreme 955EE(3.4 GHz)

Dual Processor Xeon (2.8 GHz)

Pentium D 940 (3.2 GHz)

 

The pentiums have 2x2Mb L2 Cache while the opteron is 2x1Mb

 

If I get the systems lower on the list I could get a 256MB graphics card,
instead of 128.  How big of a difference will this make compared to the
difference in processor power?  Also I could get two monitors with some of
the cheaper processors towards the bottom.  

 

Also I believe the systems towards the top have more maximum memory
available (if I go to 64 bit system)

 

Any thoughts?

 

Thanks,
