Where is your proof? I don't know where this is coming from. Windows 8 does in fact has higher gpu/cpu usage(I believe)(but not signifcantly) but the ram part you just made up. 2gb!?! With google chrome, and word up, I'm only using 0.8gb.
I didn't make up the ram usage. I'm sorry if I'm wrong but when windows 8 first came out i watched a video about it in which they actually admitted windows 8 will use 2gb ram. Maybe I missheard?
I also couldn't believe it, so maybe I did mishear... sorry
