Graphics Card Problem

[Brutorious]

I just bought a diamond 1gb Gddr3 Ati hd 4670 graphics. But wen i play the games i see that graphics of the game is the same of the card i had before which was a 256 ati video card. Is there something i gotta do to change the graphics to be of better quality? I knw there is something i can do but i dont know what i did before to make it better. I lag in moradon which i know i shouldn't be laggin like i am right now. So if there is anyone who can give me suggestions, blow me away . Thank you

Wich CPU do you have? Maybe your cpu / mobo cant handle the card and therefore there wont change much with buying an new card :P

Driver update?
Change game Settings?

if not then, you need to look at your overall pc performance,
CPU,Motherboard,
Doesnt your system meet the min requirements of the GFX card. and So on.

if you're looking for better quality in games.
Choose the highest resolution and 32/64bit settings.
