My old PC (i7-4930k, GTX970) is dead due to high frequency power shortage recently. I am thinking about getting a laptop to replace my PC. Here are my 2 choices Brand new XPS 15 (7700HQ, GTX1050 , 512GB PCIE-SSD, 16GB ram, 4K touch screen) from Dell for $2000 Canadian dollar. 3 months old Macbook Pro 15 2016 based model from craigslist for $2400 Canadian dollar. Which one should I get ? Is there any risk to get second hand Macbook Pro ? I haven't used Mac since 2013. Does Macbook still hold its value better than Dell ? I need to drive 2 4k monitors at home. Is Macbook Pro 15 capable to do that ? How is the performance compared to my old PC ? Or should I wait for Macbook Pro 2017 ? Based on previous experience, price usually drop on the second gen Mac.
