The video or the EVGA graphics card is one of the most unique and critical component of your PC. For the beginners, they may not see any use or need for such PC accessory especially when performing simple computing jobs involving web surfing or work on a document since most computers are already outfitted with their on graphics that will handle these simple and common work activities. This type of activity will not also require higher OCZ memory of your PC. In fact you can even enjoy some games by simply relying on the integrated graphics that comes with the PC basic configuration.
Nonetheless, you should understand that the integrated graphics and the RAM of your PC use the same video memory Graphic cards for gaming PC. The integrated graphics can not efficiently handle 3D applications. You will definitely find your PC inadequate if you are into some hardcore 3D based games or doing some advanced graphics editing work. In which case you have no choice but to have an applicable graphics card with the sufficient amount of video memory installed in your PC.
The earlier versions of graphics cards were integrated into the system of the PC through a compatible PCI slot. The later generations of PCs had outfitted a separate slot specifically to accommodate graphics cards. These slots are called the AGP. These new slots allow for the faster transfer of data between your CPU and the graphics cards which resulted to faster response and better performance of your machine as a video game device or as a graphic editor assistant.
The most recent version of graphics port is the PCI Express x16. This latest version of card slot provides for data transfer rate that is even double than the fastest AGPs. Most of the present versions of graphic cards are designed for the PCI Express slots. PCI Express is considered as the norm for present day graphic cards.
At present, it is quite common to see advanced gaming formats and graphics applications that require more than one graphics cards. In which case, you have PCs that have more than one card slots or ports to accommodate the requirement of these advanced applications.
The built-in video memory of these graphic cards ranges from 128 MB to a maximum of 512 MB. The video memory of graphics cards is defined as a DDR-memory. This type of memory is capable of transferring data at twice the maximum speed of ordinary memory.
At this point, it is important to note that there are other factors that affect the performance of your PC. Previously, the basis of the level of performance of a graphics card is the size of the memory. However, present generation PCs sets the level performance based on the memory of the graphics card, the type of port that will accommodate the card and the speed of the core clock, to name a few. However, the main determinant of the level of performance of your PC shall be the type of graphic cards that you will use.
