Do your research comparing Intel and AMD CPUs.  I just went though what 
you are looking at and found that AMD performs very favorably against 
Intel in multi-threaded situations but poorly against Intel in 
single-threaded situations.  It's a sad situation if you want both.  
Since you mentioned resource constraints, if you are willing to consider 
used CPUs then you will find that Intel has a better secondary market 
than AMD.  Single-threaded performance plus getting a used Intel CPU for 
less than a new AMD swayed me to Intel but you may decide differently.
