I am not acting superior in my knowledge of PC's and gaming hardware, I am actually convinced that it is !
This is the key difference, where you are trying to constantly circle back to my discounting your false statement, I am offering insight into why it is false. Also I have already answered the OP's original question and expanded on it.
If we assume the OP lives in a house/flat with no electronic entertainment hardware and start from there:
Xbox - Depending on region, we will assume US - Console with peripherals and 1 game max. $399 - LED TV Between $100-400 depending on size etc. We can safely assume if he does not live somewhere that has a TV already, he is not going to suddenly buy a 50 inch screen, is he? Even if he did those go for $400, you don't need a $1000 Samsung for this.
Laptop capable of the same GFX settings in current AAA games, running at 720p and 60 FPS - I will argue is not available under $900 - prove me wrong
Gaming PC capable of reproducing the same settings, including all required peripherals and hardware - Again, not available at $400. Potentially doable at $800, however you claimed $500...
Now, depending on region, all of these EXCEPT the console will be even more expensive...in some cases FAR more. So your argument becomes even less plausable.
And you have STILL not shown us the pc setup you had in mind to back up what you said. You are busy whining about me, rather than making a facts based suggestion.
Please show us something to back yourself up or please let it go.
