what is the budget?
for 720p, any one from these cards will do - radeon hd 5570, 5670, 6570, 6670, 7750 1 gb ddr3/gddr5. gddr5 is preferable for higher memory bandwidth resulting in better gaming performance.
i want cheap graphic card for gaming in 720p because my budget is low i dont play games in 1080p.
monitor is 18.5 inch LED.
How about you get a job (mow lawns, wash cars, etc) and save up some money? That's what I did when I was a kid. If I wanted something nice, I worked my butt off and saved up the money to buy what I wanted. A decent video card and computer monitor can be had for less than $300 today! Just do your research and you can find all sorts of deals out on the internet. Your question sounds lazy in that you can't even spend the time to do reearch let alone earn the money necessary to buy the hardware you want. Typical youth these days...always want something handed to you without first earning it....
my budget is in indian rupee so it is as, 6000 indian rupee.please be sure that all price of product are more costlier than usa etc.(because of import charges)
