way different cores.
The new 360 is slowed to the old 360s performance though. They cant have devs making games for a console and not having it run on an older system. The only thing that changed (to the user) is the look, (besides the HDD size) the performance is the same.
And it doesnt just depend on the TV. The GPU in a PC is very important here too. The consoles GPU is still based on 5 year old tech.
On topic, I have it ordered for the PC. Mods, better graphics, and keyboard/mouse.
