First Proper PC Build, Need help with gpu

ok so i have finally decided that i might put the money down on a built pc to play games mostly along with some web browsing and word processing.

so here is the link to the current build i have in my cart with exception of the gpu. as of right now i have a am2+ build that has a geforce 9500gt with 1gb of ram, but i dont even know where to start as far as a new card would go. so................ if i could some input from you guys and some thoughts on what i have.

Thanks,

Boneskid1

 EDIT: i forgot to add a budget i would for sure want to spend less than 200 and if i have to go more i would, but it would have to have a large benefit

EDIT 2: here is the paste from the cart

 

Ram:                    Crucial Ballistix Sport 8GB DDR3-1600 PC3-12800) C SKU: 211334          $44.99

That's a link to a cart....only you will see the build you posted because it's in your cookies. Use PCPartpicker or a newegg list

ah ok my bad i forgot about that,

i am considering getting a cheeper dual core like the i3 or the pentium, but if i get this biostar board it is 10 bucks with anything more powerfulll than the pentium.

I'm confused by your posting. If you are looking for a cheap graphics card:

basically i am trying to build a decent budget pc to game with and stay on the intel platform so with the parts in the above post the last thing i need to get is a video/grapics card/gpu. that is what i am asking asistance for as i dont even know where to start.

Uhh wtf? $20 motherboard? Or am I reading something wrong?

he says 20 dollars but its 80 on newegg

it is only 20 because it is bundle with the i3 to i7 cpu
