If you're a true hardcore gamer.... get a PC.
this. my system (i7-3770K, 8GB ram, GTX 560Ti) would be considered above average now, actually
good a year ago, and it still absolutely destroys the living fuck out of anything my brother's 360 can do. on paper it is ridiculously ahead of the xbone and ps4 in terms of processing power and rendering power, but in all fairness I haven't had the chance to do a direct visual comparison in person yet. the difference is while I actually only paid a little more (~$450) altogether for this box, most people who don't work where I work would probably have paid about $750-$900 for the same machine, so I understand why people go for consoles as much as they do. though I still hate gamepads for modern games; you put two gamers on identical PCs head-to-head, gamepad versus keyboard-and-mouse, playing the exact same multiplayer games, and that poor gamepadding bastard is thoroughly fucked.
