"stop saying the xbox 360 has twice the memory, you're misleading everyone.
The PS3 has twice the floating point performance of the Xbox 360, the memory you're talking about is completely misinformed.
The ps3 has 256MB dedicated GPU and 256MB of dedicated XDR system memory at ~3.0ghz The xbox has 512MB total memory with a 10MB dedicated GPU."
