I got the Intel Core i7 with 3.40GHz processing and 16GB RAM. I first started using the product a month ago, and I've been very happy with it. It runs quickly and without any apparent issues. I wanted a dual monitor setup, but the computer didn't have the necessary parts when it arrived. I contacted the seller's customer service, who provided me with Amazon links to the necessary cable splitter and graphics card, which I later installed without a problem.Some other data points is that it has a licensed Windows 10 Pro operating system and I believe the computer was first sold in 2012. The only problem I have with the computer is that it has a rather loud fan.
