I was ready to buy a Mini but the 630 GPU in the Mini has me concerned. I have a MacBook Pro now with discrete NVIDIA GeForce GT 650M so I fear the 630 might be a let down. Considering: 2018 3.2 6-Core, 16GB, 512GB SSD $1699 Latest 27" Imac 3.4, 16GB, 512GB SSD $2299 Basically for $600 you get the 5K display and much faster GPU. I prefer Space Gray but I'm not willing to spend $5,000 to get it in the Imac. I can justify $600 for faster graphics and 5k display but I am not a fan of the silver case while the Mini is a good value and comes in Space Gray. But there is that 630 GPU to consider. What do you think?
