I am thinking to buy a used laptop( still not sure though) . I am getting this one in around 530 $. Samsung Series 7 Chronos 770Z5E Specs: - Intel Core i7-3635QM quad-core processor with a base clock speed of 2.4 GHz - Dedicated GPU with 2 GB of GDDR5 memory - the AMD Radeon HD 8870M - 8 GB of DDR3 memory - 650 GB HDD - Matte 15.6-inch display with a Full HD 1080p resolution of 1920x1080 pixels. - Fingerprint-proof finish (Brushed Aluminum) with underlying keyboard back lit light. Is this price OK for it.
