Video card buying tips

               

Purchasing a computer video card can sometimes be a very confusing and frustrating task. Before purchasing a video card, keep the below recommendations in mind.

Connection

1. PCI-E or PCI-Express  is the latest computer bus found in computers. PCI Express is designed to replace PCI and AGP and is available in several different formats: x1, x2, x4, x8, x12, x16 and x32. See the PCI Express definition for a full description and related links.

                                  

2. AGP or Advanced Graphics Port, It is something old technology.Now a days no modern motherboards come with this type of port. AGP has a direct line to the computer memory, which allows 3-D elements to be stored in the system memory instead of the video memory and is available in three different standards (1.0, 2.0, and 3.0). 

                                 

3. PCI or Peripheral Component Interconnect, it also was an old type of technology first introduced in 1992. Now days no modern high end graphic devises come with type of port. 

                                             

Other considerations

Ports : check your monitor port they are different. Remember to buy a graphic card which matches with the port on your monitor.

For example if your monitor has a VGA port, to connect with your graphic card you need the same port on your graphic card also.

Chipset - There are dozens of different video card manufacturers. However, there are only two major chipset manufacturers; Nvidiaand ATI. Although both are great manufacturers there can be great big differences between the two as far as performance. Before buying any video card it's a good idea to look up a hardware review on the video card before purchasing it if you're concerned about it's performance.

Size - If you have a smaller computer case fitting some of the new video cards in the computer many not be possible. Video cards today are much larger than older video cards because of their increased capabilities and need for cooling fans. Make sure your case is going to have room for a new video card. The only way to do this is to open the case and physically look.

Warranty - How long is the warranty and what does it cover.

Price range

The price range can vary depending on the brand of video card, amount of memory, the interface used, and other available options.

Where to purchase

For best price we often recommend that users purchase all computer hardware online. You'll be able to look at other customer reviews and get a much lower price. If you're uncomfortable buying online or want to talk to a sales rep you can always visit a local retail store and then buy online.

Service Pack

                                       




A service pack, often abbreviated as SP, is a collection of updates, fixes, or enhancements to a software program delivered in the form of a single installable package. Companies often release a service pack when the number of individual patches to a given program reaches a certain (arbitrary) limit. Installing a service pack is easier and less error-prone than installing many individual patches, even more so when updating multiple computers over a network.

Service packs are usually numbered, and thus shortly referred to as SP1, SP2, SP3 etc. Windows XP has 3 service packs.

How to identify which Service Pack that you currenlty run?
