FreeBSD for Intel(r) Xeon Processor X5560

[Manju Kalita]

Hi Friends,
My Processor is "Intel(r) Xeon(r) Processor X5560 (2.80 GHz, 8MB L3 Cache, 95W, DDR3-1333, HT, Turbo 2/2/3/3)". Could you please advice which FreeBSD architecture I should use? As per the FreeBSD site, IA64 is still running on tier 2.  Could you please help me out?

What will be the performance if I go for Amd64? Will Amd64 will support Intel(r) Xeon(r) Processor X5560?

Thanks & Regards,
Manju
