CPU upgrade vs CPUTYPE

We have a small server running FreeBSD 8.3 amd64 with Intel Pentium D  
945 CPU. As the motherboard/CPU combo is getting rather old, we are  
considering an upgrade to new motherboard with Xeon E3-1230 CPU. We  
currently have these CPU settings

in /etc/make.conf:

in kernel configuration:

Almost all the software is built from ports, few bits compiled  
directly from source. Base system is maintained by buildworld.

Can we expect the software compiled with above CPU settings to run  
without problems on the Xeon E3? We had a chance recently to try a  
temporary motherboard/CPU swap in this server, replacing the CPU with  
Core i3-2xxx and there were some 'signal 11' errors, but I'm not sure  
whether this was due to incompatible CPUTYPE or something else.

Thanks in advance,
