DDR RAM
Many computer enthusiasts know exactly what they want when they go to configure their new system.
They've researched and picked out a perfectly matching CPU,
Motherboard and videocard combination that will meet all their needs.
However, when it comes to RAM many users become totally befuddled.
They generally know how much RAM they need
(1GB is the effective operating minimum these days, 2GB if running Vista or using hungry apps like Photoshop),
But they don't have a clue as to what DDR1, DDR2 or DDR3 means.
