"I'm not here to get nasty about this."

i'm not either

"It has Dedicated Ram"

i know but does that mean that the GPU can't access the other RAM? "available for te GPU.''

The GPU can access the entire memory, but it doesn't mean that it's practical in a performance way.

true, i was just demonstrating to him that it was incorrect for him to say 

"256mb Ram the PS3 has available for te GPU."...

i wonder why sony split the RAM in the first place instead of using one type like the 360
