I own a Mac Pro 4,1>5,1 (2009) 512 GB SSD PCIe, ATI Radeon 5870 1GB VRAM 16 GB RAM with a 23 inch Mac screen that is ten years old. I can buy 4 GHz Imac 27 inch retina with 512 GB SSD 32 GB RAM and 4GB VRAM AMD Radeon R9 M395X or upgrade the current MacPro with a Nvidia GTX 970 or 980 2x6pins (no 8 pins), an USB card 3.0 Calldigit driverless and a Retina 27 inch Dell display. What would you do? Use the current MacPro as a second computer and buy the Imac or upgrade the current MacPro. The first option will cost me approx. 1250$ extra.
