You would an average 9-11 frames, no use,
buy a card that can run GTA 5 at 30 fps on 1024*768
Give in detail specs of your processor, i3 6th gen 2.7,3.4 ghz?
the 2gb amd radeon is a new card or 5 year old?
4gb ram will cause the pc to kneel at GTA 5, Try upgrading your RAM to about 8GB to enjoy lag free experience
What is the speed of the existing ram and DDR3 or DDR4?
U say 6th gen i3, is it unlocked processor? coz you might wanna overclock it if its at say 2.7 or 3 ghz in stock
do you have good cooling facility?
Have you tried running crysis 3? how much frames u get with current specs? consider using crysis 3 to compare your specs power coz crysis 3 is a graphc demanding game and u might get an idea if u consider running crysis 3 with current specs and posting the framerate and resolution u get for max.
