Thanks guys

For simple minded peeps... Wp-Super Cache

For those getting into APC/Memcached stuff... W3T

For those getting really into shit with either... MaxCDN.com

W3 is pretty good

My favorite is Quick Cache, working flawlessly on 100+ Wordpress blogs

i just did w3tc on ~300 blogs. its a shit imo. didnt help at all. maybe i am doing it wrong :P but disk i/o went up big time. i activated the plugin, and turned on everything but minify [kills css on some themes for some reason..] and CDN and CloudFlare. then i 'deploy' the changes...
