CCIE exam is for professionals. CCIE lab is cpu intensive.. Hence wanted 8 core processor .. So what basic gpu will be sufficient with 2700x?The number one thing I ask for is use case. What will you be doing? If its video editing then you might need a beefy card, but if its office work a basic GPU will suffice. Also, I doubt you will need much horsepower for "CCIE Prep" since isn't that like schoolwork?
Th GTX 1660 replaced the GTX 1060 6GB. If the 1660 is cheaper then go with it instead.Thanks for the suggestion. I"ll go for gtx 1060 6g
