I really can't rate it for gaming because I don't play online games.I can't rate Tech Support. Absolutely NO problems.This replaced an i3 computer that was driving me crazy.It was slow and kept freezing up and was just terrible.The old computer took 6-7 minutes for a virus scan.The Lenovo does the same scan in 26 seconds. That's 10 to 15 times faster.The Lenovo has plenty of slots for expansion.Lots of USB ports. It's quiet and very fast.I think that the Lenovo is the best computer for the money.I just really like it!
