I completely agree with this and anyway many of the caching programs are starting to understand that nginx is out there. I am pretty sure w3 total cache does.

However since using nginx I have done away with caching as it is so much faster than apache + caching that I don't really need it.

That's my point. For any small/medium sites, switching to NGNIX will make a dramatic improvement on all aspects of your site, while dicking around with caching will cause you endless headaches.
