should I change to multicore CPU??

Hi,
 I know that freebsd7 has huge improvement on multi-threading
execution. I wonder if I upgrade to 7, would I feel it?? I now own a
amd64/3400+, running 6.3. It's just personal use, download files,
watch movies, etc. I guess it will be faster on multi-core when I run
mencoder to encode movie, but aside from that, will it mike much
difference to me?? thank you!!
