First of all, where can I see some pictures of a stock n75 vs a Race n75? I'm not sure what I have... And is an n75 worth it with a ko4, giac pc-16, and all the stuff?

 

Whatever you do.... DON'T get the ECS N75 Race version.
It gave me more problems than anything. Massive hesitation and hick ups and stumbles. Just SAY NO to Race N 75. Any performance gain is not worth the problems it causes. Get a Boost Machine instead.
