Recognize your memory what to use slot SIMM or DIMM? Clock of RAM also must equal to clock motherboard so that be got maximal work. If you use the two RAM, use the same clock RAM if one of lower clock so overall RAM will put the loyour clock.

Processor
Replaced processor newly represent the way of very often done but there is matter which require to be paid attention that is your motherboard have support the bus speed from processor. Clock Speed from processor the sooner the better.

Hardisk
Good Processor and big RAM it is true will improve the work of computer, but so that can work eminently is of course required storage media with the big enough capacities.

For game devotee quality of graphic card very influences game performance. upgrade graphic card wanted when game you play to belong heavy game. Necessary you look at speed from RAMDAC of graphic card. Faster RAMDAC so more softer display of picture that produced. Choose graphic card with RAMDAC speed minimal 250 mhz and don’t forget to always update newest driver of graphic card. But for you merely use computer to type so upgrade VGA not important.

Port
