What were you using for a graphics card?


One of the big limiting factors is going to be your PSU.  It looks like your PSU is a 305W @ 18A.  This will limit your choices unless you change out the PSU as well.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

What type of case does your OptiPlex 755 have??


(the options are mini tower, desktop, Small Format Factor, Ultra Small Format factor)


If it's USFF you can't fit a graphics card.

If it's SFF you can only fit a very compact half height card with a very low power consumption that's powered through the PCIe bus. PSU will only be around 275 or 235 watts. 


Desktop is I believe similar to the SFF but I've never been in one so I'm not sure.


Power supplies for all the above are Dell specials so cannot readily be upgraded.


The mini tower has room for most cards and has an ATX type power supply, so that can easily be upgraded.
