How mich in the price of gigabyte-gforce 7300 graphic card?

Answer 1

A Gigabyte Geforce 7300GT is $82, http://www.newegg.com/Product/Product.asp?Item=N82E16814125036

I do not recommend a standalone 7300GT as your only solution. If you can get two 7300GT graphics cards and use SLi on them, that's not too bad performance. If you only have one PCIe slot then I recommend either the 7600GS or optimally, the 7600GT. Anything beyond that is wasting money, especially this late in the game as the DirectX 10 enabled 8 series is due out this fall.
