As I'm not in your country, supply what you can get.
I have a Lenovo M90 i5 Desktop with 1TB, 8gb & runs win 10, recently I've been having issues with the graphics card and am looking to replace/upgrade.
This is my work machine, so work load is usually MS Office & social media clients with occasional photo editing & youtube viewing.
I've also also just changed monitor to a 23' widescreen with an HDMI socket, so would like the new card to be able to utilise this and possibly in the future go to a multi monitor format.
Not looking to break the bank on this, so looking at budget of about £100.
This is the current card: https://support.lenovo.com/sg/en/solutions/migr-69080
