I'm building a new server with 7.0 BETA4 (it will track stable) with  
the following CPU

CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ (2600.02-MHz K8- 
class CPU)
   Origin = "AuthenticAMD"  Id = 0x60fb1  Stepping = 1
    
Features 
=

,PSE 
,TSC 
,MSR 
,PAE 
,MCE 
,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2,HTT>
   Features2=0x2001<SSE3,CX16>
   AMD Features=0xea500800<SYSCALL,NX,MMX+,FFXSR,RDTSCP,LM,3DNow!+, 
3DNow!>
   AMD Features2=0x11f<LAHF,CMP,SVM,ExtAPIC,CR8,Prefetch>
   Cores per package: 2

What optimizations should I make in make.conf?

The example make.conf says

   AMD64 architecture: opteron, athlon64, nocona, prescott, core2

But I don't know whether althon64 or core2 would be the safest and  
most appropriate.

Also GENERIC for amd64 lists

     cpu    HAMMER

is that the best (only) choice?  And if not, where can I find a list  
of alternatives?  I didn't find anything in the NOTES files telling me  
what was available.
