If you are supposedly so knowledgeable about game creation, you'd know that GFLOPs are not the be-all, end-all of game production, especially when it comes to actual implementation of code and the fact that the PS3 is bottle-necked up the ass because of its RAM/VRAM size and speed.
I'm not knocking God of War, it's a beautiful game, just like all other GoW games were in their time. But compared to a PC? Nah. The texture resolutions, framerate, and many other aspects of the physics and lighting engines just can't be done on a PS3 compared to the raw power found in a nice gaming rig. PS3 (and all console) games are more optimized because of their singular platform but the sheer processing power and RAM in a PC outstrips all of that by a wide margin.
