I was looking for a good and powerful laptop and found this in Amazon at a great price. I had my doubts on purchasing it but when i read all the good reviews, I went for it. I also bought a Samsung SSD 860 EVO 1TB 2.5 Inch SATA III Internal SSD (MZ-76E1T0B/AM), Highfine Universal 9.5mm SATA to SATA 2nd SSD HDD Hard Drive Caddy Adapter Tray Enclosures  and a Samsung ram memory 16GB kit (2 x 8GB) DDR3 PC3L-12800,1600MHz, 204 PIN SODIMM and installed everything.The Samsumg software to migrate the system to the new hard drive work flawlessly. This laptop is a beast and a megathlon with the upgrades I added to it.Speedy delivery and worth every penny I paid for it. It saved me approximately $1200 compared to a new laptop I was eyeing with almost the same configuration as this one.  I would give it 6 stars if I could.
