Umm, PC's cant handle emulating an Xbox360 or PS3 at all. To emulate, you need 3-4x the power of what you are emulating. This is especially since the games are programmed for the hardware of the console, when you emulate, it is software based, and in order to run the software that emulates the game engine, it takes a lot more power.

Consoles own.

"why I've gotta be one of the cool kids just to walk by/
- without being tripped, thrown down on the ground and kicked/
Insulting me for no reason, I was treated like shit/
The teachers let it happen/
I've even seen some of them teachers laughing/
That's why I had a smile on my face when I started blastin/" - Ill Bill - The Anatomy of a School Shooting
