I am stuck between a Lenovo Thinkpad Yoga 14(i5 4210U 1.7 GHz, 8 GB RAM, Nvidia GT 840M 2 GB VRAM) or Lenovo Y50(i7 4710HQ 2.5 GHz, 8 GB RAM, Nvidia GT 860M 2 GB VRAM). I know that the Y50 has better gaming performance, but I also need a laptop that will last me at least 5 years. Therefore durability is near the top of my list as needs, as I am a student. I also am a bit skeptical of the Y50 battery life, as I am not sure 4 hours is enough for a student. I also want to do some gaming, specifically GTA V, Skyrim, and Battlefield 3. I don't mind medium settings either. Also is having a touchscreen a huge plus on Windows, as the Yoga has one? Right now these laptops are at a similar price point on eBay. Thanks for your help and have a great day.
