Kernel Config Recommendations for AMD Chip

[Michael K. Smith - Adhost]

Hello All:

I've spent my entire FreeBSD life in /sys/i386 using Intel chips.  We
have a new server with the AMD processor listed below and I'm wondering
if:

1) I should stay in /sys/i386 with different configuration variables; or
2) Compile out of /sys/amd64

Any insights would be greatly appreciated.

CPU: AMD Opteron(tm) Processor 240 EE (1396.03-MHz 686-class CPU)
  Origin = "AuthenticAMD"  Id = 0xf5a  Stepping = 10
 
Features=0x78bfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,
MCA,CM
OV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2>
  AMD Features=0xe0500800<SYSCALL,NX,MMX+,LM,3DNow+,3DNow>

Regards,

Mike
