In the last twenty years I have purchased over 100 Dell computers exclusively because they easy to maintain. This 780 C2D E8400 Windows 10 has been so unusually slow (5 minutes to start) that I have had to replace it with a new Dell 7020 i7 with 32GB RAM and SSD. Everyone who has tried to use this computer has complained about it slow operation. At 81 yo I don't live long enough to wait for the 780 to perform.
