      The motherboard and CPU speed is what really determines the ultimate speed of your PC. You can add RAM and that can help a lot but if you really have an older PC you might have to resign yourself to buy a new one. But if you want to try to salvage an older PC you can upgrade the video card and RAM to see it that will help. If you are considering upgrading your RAM there are utilities that can determine the best configuration for your system. RAM is also pretty cheap so you won’t be out a lot of money even if it does not improve your systems speed that much. You must be sure that the memory you purchase is compatible with your system. You can check your computers manual for specifications. Before you upgrade your video card you also need to find out what is compatible with your computers motherboard. You also have to be sure that the power supply is capable of handling the added power that it will consume.
