Depending on what type of user you are, a performance graphics card is sometimes necessary, so that the latest games runs smoothly and with high quality. However, before buying, make sure to check whether your motherboard is compatible with the new card. Some high performance models actually take up the entire length of the PCIe slots even on a ATX sized motherboard. Therefore, you should make sure if it actually fits into your computer chassis. Sometimes the hard disk cages or the fan of the CPU and the cases can get in its way. These days, the connection technology will never be an issue: as the PCIe connection has been a standard that has been established for many years. However there are several different revisions. To ensure that the card performs to it fullest, you should compare the specifications of the motherboard and the graphics card before making a purchase. The installation is usually not critical. But older drivers can cause problems. So before you start working with driver removal tools, you should consider a clean reinstallation of the system. This often solves all the problems.
