[inconnu]

so i have a hp 500-164 model and it is stock. the spec is amd elite quad -core a8-6500 accelerated processor, AMD radeon HD 8570D graphics, power supply at 300watt and window 10. i am playing the game mostly at like 7-20Fps. in dungeons and usually play under 10 fps. i was wonder if i switch the graphic card to GTX 750Ti will it improve my fps to like 50-60 at like low and medium setting in like dungs and arena, i dont really care if i get low fps in raid or event areas, or any suggestion on what to replace to get my fps up. thanks
