The speed of I7 operation selected by CPU is enough. Take care of both office and games. The latest memory of the motherboard supporting 2400 frequency is absolutely enough to do some necessary program calculus. The graphics card is 760, 4 ports, you can enjoy the game world after work, and you can also display 4 screens with the card. Mechanical hard disk 4TB, convenient to store some quantitative data and historical trend data. SSD solid state disk mainly supports real-time operation reading speed. Convenient for a large number of multi-task operations and reading. The stability of power supply selection is the first great wall. Philips' 24-inch X3 or 4 is selected as the monitor, because it is not a professional drawing, which is generally enough. The choice of sound is a luxury of hivi. Enjoy some music to relax after work. The whole package is 1.5 million, but this is the online price. You will be much cheaper in a physical store. And the after-sales service is also good ~ I hope I can help you. I didn't choose the best graphics card because I had enough entertainment after work.
