Terry, I've been x64 since Cakewalk 7 and Vista. I wouldn't go back. I miss nothing. 32 Bit Plugs work when I need them, which is less and less. I didn't buy J-Bridge, but some advanced users have said J-Bridge has helped them keep using some of their 32 bit libraries.
Perfect Space and VC-64 are two 32 Bit Plugs I use regularly. The only minor side effect of the 32 bit plugs is that if I save the project during playback, I can sometimes hear a pop. That's the worst of it in my opinion.
I would never consider getting a new computer and go 32 bit.
