the best graphic card is Nvidia GeForce 256MB or 512MB find out latest version in market its the best graphic card for 3D games and also gives better quality of display never hangs many new advance graphic cards are available in market but they hang if ur pc doesnot gets proper cooling and have a chance of getting burn i m using Nvidia graphic card since 3yrs and its running smooth

u hav good configuration of graphics it is Good for normal gaming Nvidia is good but not best u can use world's best ATI graphic cards HD 2950 series X2600 series or many more search from http://ati.amd.com/products/index.html

I guess your bus interface is PCI Express Therefore, for serious gaming get a Nvidia 9800 GTX or an ATI HD 4800 series.
