The cpu is OK. I would not worry about that. The gpu is decent as well, but will use more power than an equivalent current gen one. I agree, the biggest weakness is the 8gb of ram, but again, it should be usable. You could upgrade the ram and dgpu later as budget permits. I have to admit though, the the whole situation seems a bit sketchy. Does the seller have legitimate rights to sell the PC? He may, but I have worked for both the federal government and a major university, and used computers are turned in to the IT department and trashed, as wasteful as that might seem, not put up for purchase by employees.
