I have been dealing with Interaction computers for over 10 years. From gaming machines to office machines for my staff.
When you go to interaction, you're dealing with pro's that know all the latest intel on the industry. There was a time a few years ago that it was easy to keep up with the changes...now, it's changing weekly, not quarterly.
They also serviced my machine when I had a problem one time. It kept doing BSOD (Blue screen of death) It was troubleshooted to be the ram which they replaced at no cost for parts/labor.
Highly recommend vs futures shop or any big box computer giants.
