Building a PC

Hey guys!

So basicily, I want to build my first gaming rig. Usually I just buy the pre configured gaming machines (ibuypower). Im pretty familiar with how to put together a PC and what each part does. My question really is what do you all recommend as far as parts go. What brands would you recommend and which should I stay away from? Strudinox recommended I go with a Nvidia/Intel setup. Any opinions on that?

cheers!
