I have been collecting parts for an Unraid system.  I have purchased the MB (P5LD2-VM).  I am struggling with what processor to purchase.  I was looking at TheMAster's specs http://lime-technology.com/forum/index.php?topic=378.0, but was wondering what just a little more money spent on the CPU may do for my UnRaid system.  Seems like the target is 2 GHz or higher.  What about the Front Side Bus Speed?  Would there be a drastic difference between 800 and 1066 MHz?  I am looking to get the most bang for around the $150.00 range.  Thanks for any input.  I am willing to spend the same amount on Memory also.

I personally get pretty good performance with my 4 year old dual processor Athlon 1600. At least I think they're 1600 MP.

Thanks for your input.  I decided I would go with TheMaster's pick:

 

Intel Pentium D 820 Dual Core 2.8GHz, 800MHz FSB

1GB Dual Channel Corsair XMS2 PC5400 DDR2 675 SDRAM

 

I am sure I will get good results.
