I just got Diablo 3 and my graphics card is one of the ones that wont even let me start the game, I looked up found out a way to bypass but the game does runs really bad. I have it running in window with all of the settings on low and the game still lags when I get into combat. I am looking for a cheap graphics card that can run this game (about $20-$50). I dont know much about this so any advice is helpful
