Hi guys, i have a Asus - Desktop - 8GB Memory - 1TB Hard Drive with the GPU of AMD HD 8350 (intergrated). I went to game stop today and bought Assassin's creed : Black Flag and realized that i cant run the game smoothly. I probably can't return it since i have opened the box and activated the code. Is my computer capable of installing an actual graphics card. If so, what card should i get?
