Currently I have 32bit non pae and 64bit running neither are slowing
down for me, the other thing you can try is running in unity2d or
leave top running and see what is happening memory wise.

I'm only assuming pae may be the cause I'm not saying it is,  you
maybe running apps that have memory leaks and that is the issue hence
the leaving top on all day to monitor it.
