Is it worth it to get a graphics card?

[ThunderDragoon]

Even though I've tried CYRI and it says my computer can run the game, I still get the renderer #0 error. I've checked almost all the threads on this error and nothing has helped. So I've come to the conclusion that I need a graphics card, but is it worth it? Is it really worth paying over $100 to play just one game? I'm thinking of just returning the game. I don't know. I thought I'd ask here before I do anything. I've spent so much time doing different things to fix this error and it's getting really old that I can't play a simple game. Any input is appreciated. Thanks in advance.
