anyone running this game with amd radeon 6670?

[Loii]

my current graphics card struggles with this game, and I was wondering if this card works well/better

my specs:
intel core i5 3.2ghz
3gb ram
ati radeon hd 5450

I run with a 7870 card and it runs max settings with 60 fps constant. If you can get afford it I would go with a 7870 they are around 230 on newegg when I bought mine. Also if it is possible I would up your ram as well. I am not sure of your budget but it will make the game run a lot better and help with future upgrades to the game.
