Last year I bought an Optiplex 755 and installed a Nvidia GT 710 to allow me to play Flight Simulator X at a high standard and the performance was amazing for the money that I had spent. Recently my brother upgraded his graphics card which allowed me to have his old GT 710. I installed it in the computer and installed the necessary drivers and it worked but when I launched Flight Simulator X, the performance was terrible, the graphics were trash, the FPS was low and the sound was all messed up. I spent many hours trying to figure out what went wrong as I thought that the GT 710 would be an upgrade from the GT 210, not a downgrade. So please could one of you perhaps show me where I am going wrong, thank you.
That model has a very small power supply. The GT 710 requires a psu of at least 300w as does the GT 750. Amazing that you got it to work. You should mention which version of the 755 you have. There are 4! All have small psu's.
