Tried CSS out on low settings (theres really no point in high settings as Its barely noticable with the screen) on native resolution, joined a 32 man deathmatch server and ran like a champ. I didn't record the FPS, but It was very smooth.. 50-60+ fps constantly whenever I looked at the fps.
Oh, and It has proven Its battery life to me for my needs. It genuinely gives out upto 9 hours on light usage. Lasted me about 5-6 hours whilst gaming, transferring 90GB of data from my portable drive to the HDD, installing everything I needed, internet browsing and trying out performance of all sorts of different apps like photoshop, illustrator, visual studio etc. Its quite amazing.
And I absolutely love the keyboard on it. Best keyboard on a laptop I've ever used in my life.
