About Graphic cards

 If you don't have good graphic cards, let me give you some information so you can get a good one.

 1.If you have Intel Pentium Dual Core(1.6Ghz),

 I recommend you to buy

 Intel Pentium Quad Core, not graphic cards, because even you have a good graphic card your CPU will not support this card. This means you cannot play high specification games even you have a high quality graphic card.

 2. If you have Intel Pentium Quad Core,

 I recommend you to buy

 Nvidia Geforce GTX 650, or higher than this.
 AMD Radeon HD 7870, or higher than this.
