Because php 5.x already runs as a cgi, do you still need "PHP suEXEC Support" for good security?

Also, is this a good combo, or am I over doing it by selecting both suEXEC and PHP suEXEC?

(Looking for the most stable, compatible and secure combo here.)

Mysql 4.1.21 with php 5.1.6

Compiling apache with both:

PHP suEXEC Support

and

suEXEC Module
