could someone please find out how good a eyefinity radeon hd 7570 graphics card is?
Not very good compared to the other cards in the HD 7K series. If you need a card that can handle HD video decoding, that'd be one of them.
If you're looking for low/mid-end gaming, try a 7750.
I have a Radeon 7950 and my friend has a 660 ti and he is getting a better framerate then me in Saints Row The Third. Does anyone know possibly why?
The video card isn't the only thing that matters, your processor could possibly be bottlenecking you. Is the difference great or menial? A full spec list of both computers would be nice.
