Several users already reported it is GDDR3 indeed, the laptop does not sport GDRR5 as stated. Also, the resolution is 1920x1080 because of the 16:9 ratio of the screen.
Asus gaming notebooks (at least new ones since G50) include turbo mode that allowes up to 25% overclock for CPU (depending on CPU). This Asus W90 comes with a 2.8ghz but its max CPU speeds are 3.3ghz I believe. With stock drivers it scores over 15k 3dmark06 score, and a user with a quad core at 4ghz on this laptop (it is quad core compatible) achieved over 20k 3dmarks. As someone said to me "this notebook puts a lot of desktops to shame".
Definetly an awesome deal for the price. I would get one myself, but I am currently happy with my Asus G50, specially since my 9800m GS is still able to play anything 😛
