Im sorry for asking such question, but I am not too familier with computers so I am trying to see if someone will be able to help me. I currently have a dell optiplex 980 with ati radeon hd 3450, which is not compatible with Wins 10. So I am trying to find an inexpansive replacement. I found an AMD ATI Radeon R7 250 2GB PCIe x16 (https://www.ebay.com/itm/Dell-FDT1K-AMD-ATI-Radeon-R7-250-2GB-PCIe-x16-Low-Profile-DP-DVI-I-Video-Card/143211496157?_trksid=p2485497.m4902.l9144) and wonder if this can work. What about an AMD Radeon R5 240 1GB (https://www.ebay.com/itm/Dell-AMD-Radeon-R5-240-1GB-DVI-DP-DisplayPort-Low-Profile-Graphics-Video-Card/163650663373?_trksid=p2485497.m4902.l9144). Also if it does is it plug and play or do I need to pre-install something? Thank you so much!
