Maybe it would be easier to just upgrade your NIC's to some intel "em"
ones, it have low interrupt usage, don't know about bge on high usage.

Our company expanding, so I noticed what "interrupt" in top sometimes
jumps to 30-40%, and always about ~25% in average.
Server is DL360 server with bge0 and bge1.
So I want to upgrade to newer multicore system.
Can it help? Is it possible to assigne one NIC to one core,
and other to another?
It isn't possible. Look for the fastest CPUs, not the highest
number of cores, and run a uniprocessor kernel.
I'm not sure if they're valid, but I've read suggestions that
amd64 CPUs may be better for this type of workload due to
the larger L1 (not L2) cache.
If you feel like testing, compare i386 and amd64 kernels and
post the results, there are people who would be interested to
know...
If you currently run a pre-4.2 OS, upgrade it, you should see
improved performance just by doing this.
