Few students will see more of a performance boost after adding DRAM than gamers. Games are becoming increasingly DRAM hungry, requiring at least 4GB or 8GB and carrying developer recommendations of at least 16GB to maximise graphics and enhance gameplay.
Those games also chew up storage, with several anticipated PC titles expected to require 80GB or more, meaning gamers without drive space will have to delete older games and save files to make room for the new. Upgrading with an SSD will make sure you have enough space for all your games. Also, switching from HDDs to SSDs means gamers will wait through shorter or non-existent load screens each time they boot up the game or access a level or save file.
