When dealing with replacing graphics cards, in any system, it is imperative that you know the various types available. The variety is so great; this could turn into an overwhelming project, without the right information of course.

The most common, these days, are the PCI-E(xpress) cards. Your computers motherboard has to have an open PCI-E slot for you to take advantage of this advanced piece of technology. PCI-E cards are on the higher end of graphics and are for those who desire / need high end graphical outputs.

AGP cards are not quite as advanced as PCI-E slots; but are almost as common. Again, you will need an available AGP slot, on your motherboard, to utilize this type of card. Once this has been determined, you will need to know the max speed your motherboard can handle. When buying this card, make sure you do not exceed this speed; otherwise the card will not work with your system.

PCI cards, like the others discussed, fit directly into a PCI slot on your motherboard (no other type can be used). Most likely you will not be dealing with a PCI card unless you have an older computer. PCI slots/cards have been outdated for some time now.

Integrated cards are not something you can upgrade to, instead, you upgrade from integrated cards. These are the standard cards used by computer manufacturers, and offer the lowest graphical output on the market. They are; however, easy to upgrade from. Simply find out what slots you have available and move from there; there is nothing else to it.

Upgrading graphics cards can be a time consuming task, when it comes to variety and options anyhow. Prepare yourself, ahead of time, for the type of card you can use, and you are one step ahead of the game. Knowing what you are looking for and what you want to see will help in making your final decision.
