Is APC opcode caching worth it?

Okay, so I've got my own dedicated server through HostGator that's running CentOS and is a typical LAMP setup. I've got a few WordPress sites on the server and I recently installed and configured the W3 Total Cache plugin for WordPress.

With this plugin it lets you take advantage of several methods of caching (for page cache, database, object, minify, etc.) and some of the methods include disk caching, APC (opcode) caching, and Memcached.

Now I've been reading A LOT about this and from what I've read (and been told by the Linux System Admins at HostGator) APC would be worthless to install. They mentioned that since my server is running PHP 5.3 it wouldn't make much of a difference since this version of PHP includes it's own type of caching similar to APC. They also mentioned that PHP 6 is going to include APC built in by default.

So, I guess my question is would it even be worth it to configure APC opcode caching on my server for my WordPress sites? Or, would it just be better to stick to the disk caching method?

Just looking for some advice, thoughts, and opinions. Thanks in advance!

php 6 ..may never "happen" ( in the "will be running" sense ..due to dissent, politics, "stuff" )..search it and see why..

Otherwise I tend to agree with your sysads at HG ( with whom I also have some hosting )..5.3 does close enough so as to not require you installing APC..

I'll do a search on PHP 6, I wasn't aware of that.

I'll hold off on APC in that case, just wanted to get a second opinion. Maybe I'll try playing around with Memcached.
