Dell Studio XPS 16 Review:
So I bought the Dell Studio XPS 16 for college, and since I’m a gamer and don’t want to bring a desktop to school, I bought this laptop.With Intel 2 Duo T9800 (6MB cache/2.93GHz/1066Mhz FSB) ATI Mobility RADEON HD 4670 1GB, 500 GB of HardDrive space, and 16″ of FULL HD 1080×1920 RGBLED, how could I say no? Although this laptop was a bit pricey , I think it was well worth it.
I bought it through my school’s discount of 7%, which saved a lot of money.
