Optiplex 3010 upgrade for gaming?

Hi. Awhile ago I bought a upgraded Optiplex 3010 with the following specs:

Dell Optiplex 3010 MT
Intel Core i5-3470 3.2GHz(4 CPUs)
8GB Ram
NVidia GeForce GT 610

I'm using a BenQ GL2460 just so you know.

I want to upgrade it to a higher graphics card but am not sure what would be compatible. I have seen some videos but want an official answer if specific parts are right and some suggestions on what to get. 

see this video:

I want to just play games like Minecraft(HD) Maybe Skyrim SE and Batman Arkham games (already run OK) and stuff like that while recording with Camtasai.

I'm sorry if I havn't supplied enough information as I am not an expert. 

All the help is super appreciated!
