Is it worth it to get a graphics card?

[ThunderDragoon]

If you enjoy playing lots of games then you should invest into your computer, for future's sake.

That's what I'm saying though. Should I get a graphics card/new computer just for this game? I don't buy games for the computer. I'm a console kind of guy. If this game was on a console, I would've bought it on one of those instead. Funny thing is, when I tried this game on my friend's computer (which I know has all the requirements), it gave me a different error. One that's not solved on here yet. Maybe I'm just not meant to play this game. Say I do get a new computer. What happens if everything is up to date and I still get an error? It just seems like a lot of hassle, and time wasted, for one game. It sucks though because I've been reading about how good this game is. I don't know what to do.
