It doesn't...
On a decent gaming PC it looks so much better, and always will.
I have a gaming pc, 360, and a ps3, so i'm not some fanboy with just my 'favorite' Also, i'd love to see a 360/ps3 try and run 3 screens at that res, i doubt it would do very well...
Anyway, that level is fine. If it 'influences' someone to go and shoot people, then that person was fucked in the head already!
