It's possible -not really sure- that the lappie mobo would support a discreet AMD video card. Asus has near-exact same models that feature the R7 M265 in dual-graphics with the A10-7400p APU.
You can sometimes find new laptop graphics like the R7 M265 on Ebay and the like. Other discreet laptop graphics like the HD 8750M would work (not sure a bout dual-graphics with that --- it's an older version of the M265) or even low-watt nVidia mobile graphics <--- definitely no dual-graphics, there, unless there is a **DX12 Miracle** in multi-GPU setups.
You won't be a gaming monster on the APU graphics engine, but at 720p with low-medium settings you should have some decent 'game'
