Hi, I found a used MacBook Pro 15” 2015 with 50 battery cycles count (i7 2.5GHz - 4 cores / 16GB / 512GB / 2GB GPU) $1414 Or a new MacBook Pro 15” 2018 (i7 2.2GHz - 6 cores / 16GB / 512GB / 4GB GPU) $2337 * Prices with TAX 7% I’m a Computer Science student and I work also lightly on Photoshop and I need to run Windows on Parallels Desktop. Which one you recommend me to buy if I’m planning to have the new generation in 2020 or 2021? Will I lose the same amount in 2015 & 2018 model if I sell it after 3 years? I’m really hesitant. ****** UPDATE ****** I decided to go with 2018 15” model 2.2 Ghz / 1TB / 555x Do you suggest to upgrade the RAM to 32Gb? Will I notice the difference between 16 & 32Gb?
