The excellent Lenovo Y580 with a blu-ray burner and 500GB 7200RPM HDD. The Y580 has a good build quality, good gaming performance with the GTX 660M and I7, nice glossy 1080p screen with good viewing angles and 91% sRGB color coverage, blu-ray burner and 1TB 5400RPM HDD and a backlit keyboard. There is another model with a 5400RPM HDD, 16GB mSSD and no blu-ray, but I think it is less cost effective.
The Y580 can run 4-5 hours surfing the web through WiFi which is quite good. So, all in all, you get a very good package if you want a 15.6″ gaming laptop with a lot of features AND a good battery performance.
