Even the 3010 is going to have a 3rd gen Intel processor. It could be one without graphics though.
But if you are gaming, then you want an RX550 or GTX1050 as a minimum. You could drop down to GT1030 or GT740 or Radeon 530. The problem with buying the cheapest cards is that you are usually only $20 away from getting double the performance.
Those cards are all below the 75W limit of a PCIe slot and don't require power connectors directly from the power supply, which you don't often find in OEM computers.
