[newbie] Mandrake or Red Hat

[Hugo GONZALEZ]

     Hello.
     
     I am going to build my own computer and I want Linux to be the OS. I 
     have a CD with Linux Mandrake 6.0, but a friend offered me his Red Hat 
     6.0. Could you please tell me why should I stay with Mandrake?
     
     I'll use my box mainly for gaming and rendering & raytracing, and I 
     want a really good video card. What is the best option for Linux? I 
     was thinkin on some Voodoo card.
     
     Thanks.
