Recommendation: good file compare program ?

Hello 
As newbie I was experimenting and trying somewhat incomptently ;-)

Especially I am struggling with the ATI Radeon 7500 notebook display 
plus an external 17" TFT ...
... and the best / correct settings for the wired plus wireless NIC:
Prism 2.5 & Intel Pro/100Ve !!

Now it noticed MORE than 11 xorg.config's in its folder ;-O

What is the best program to compare 2 of these files i.e. 
the first (system inst set) and my current one ???

TIA for your assistance and suggestion/s.

Cheers, svobi
