I can't comment on gaming or tech support since I haven't attempted to download or play any games. This computers primary function is to run my business. As far as tech support, I have my own IT guy so I didn't require any tech support so far but I can say everything went so smooth my IT guy didn't spend more than 1 hour converting my office from the old computer to the new computer and that included actually taking the hard drive from my old computer and adding it into this new computer so I can say this computer was super easy to expand with an additional hard drive and it was the smoothest transition from an old computer to a newer computer that I have ever experienced and so far I am absolutely thrilled with the new system. The easy transition, the awesome price and the vastly improved performance make me think I should have done this upgrade sooner. Only time will tell if this computer will also be as durable and dependable as my last but several weeks in now and I couldn't be happier. I'm now thinking about upgrading my personal home computer too.
