Stock psu of 240w is a bit weak to support more powerful gpu. First upgrade psu to 360w to 500w.  It looks like Dell does not offer such psu upgrade in the optiplex  series 4 up to 7070.  In 7080 (optiplex series 5) Dell begins to offer 360/500w psu upgrade. motherboard upgrade is difficult because of the proprietary chassis.  A cpu better than 7700 would be i7-8700 or higher.  Motherboard for 8700 includes optiplex 7060.  3050 board IO is similar to 7060 but not identical. But you will need to look closely to make sure before planning upgrade. [IMAGE] 3050 [IMAGE] 7060
