What Graphic Cards are compatible with my computer

Hello,
I have a emachine computer with a gateway model 3507. I need a new graphics card for gaming. The card I have now is a Nvidia 7300 LE. I think the power wattage is 300. What kind of graphic cards are compatable ?

With a 300w psu, you'd probably be looking at cards like the 7750 or 667.

What is your current processor? You will probably have to go with a Radeon HD7750.
