Looking for a gfx card :x

[MaVe]

Hi,

I'm thinking to change my graphic card which should be under 200$ and should be enough to run all games.
How about Radeon HD 7750?
I have heard nvidia gpu are better than radeons.

Here my pc specification.
Intel Core i3
500 GB HDD
4 GB DDR3 RAM
1GB DDR3 GFX Card.

Here's something to direct you to the right tracks on today's graphics cards - the higher score the better.

You should be able to run games on a 7750, but if I were you I'd go for at least a 6850 in order to actually enjoy playing the games, too.
