R help - Jan 2012 - BLAS

I'm setting up an Ubuntu?virtual machine?that will use 4-Intel Xeon CPU
x5650.?
I'd like to compile R with a BLAS but the question is whcih one.? Seems 
like the only free ones are GotoBLAS which I'm not sure is being maintained 
for newer CPUs and OpenBLAS for Loongson CPUs.? I saw a favorable report 
on OpenBLAS
(http://www.rochester.edu/college/gradstudents/jolmsted/files/computing/BLAS_Comparison.pdf),
but I'm not sure it's the right thing for my CPUs.? The webpage for
OpenBLAS
says, "On X86 box, compile this library for loongson3a CPU."? Any
opinions
on whether this will work?? If not, any suggestions on another free BLAS?

I've been using ATLAS (http://math-atlas.sourceforge.net/) with good
success.
