ATI Radeon HD3600 Series

• These are mid-range PCI video cards that cost approximately $50. If you simply want to replace the video card because of a failure then this card is an appropriate option. These are easy to insert in one of the available PCI slots in the Dell Inspiron 530S. It has a video memory of 256 MB and can support up to 2 monitors. The ATI Radeon HD series cards allow you to work with any application, play games that only require normal video capability and watch the Blu-ray DVDs.
  
  

AMD Radeon HD 6670

• If you are a modest 3-D gamer, you may want to consider the AMD Radeon HD 6670. This card costs about $100. It is an entry level gamer's video card, but it does require a larger amount of PC power to function. When the card is installed, it blocks another PCI slot because of the larger sized attached cooling fan.
  
  

NVIDIA GeForce GTX 560 Ti

• This is a mid- to high-range performance PCI video card that costs about $250. Its video capabilities work well with high-performance 3-D games. It requires the standard 500 watt power supply that comes with the Dell Inspiron 530S. One negative aspect to the card is that it blocks a second PCI slot when installed.
  
  

AMD Radeon HD 6990

• This card is picked as an editor's choice in PCMag, but it comes with a heavier price tag of about $700. It has a dual video processor and uses a great deal of computer power. The card must be connected to two eight-pin power adapters so that it can get the power it needs. It is a longer PCI card but because the Dell Inspiron 530S has a roomy case, it can be easily accommodated. If you are a die-hard gamer, then this card suits well.
