4.5 GB GDDR5 of ram for games? Honestly even this is too much considering it's GDDR5 and not DDR3. I don't think devs (specifically multi platform devs) would have taken advantage of the so called "7 GB ram for games" so it would have just been a waste. Better to put some more on the OS to make it super quick. 3.5 GB of GDDR5 for the OS this thing is gonna be lightning speed lol!
