My system is about six years old now. Did most of the build myself, under the close supervision of my IT buddy, whose instructions I followed to the letter.
3.50 gigahertz Intel Core i7-4770K
Samsung SSD 850 EVO 1TB
ASUSTeK COMPUTER INC. Z97-A Rev 1 motherboard
16K RAM
NVIDIA GeForce GTX 1080
Still runs great and I haven't had any issues with it. Which is good, because I understand PC components are currently in short supply and ungodly expensive.
