I would like to know a few things. First, in a RAM, what is DDR, what is the importance of the FSB like, 533, 266 etc. and how can it affect the performance. Is a 512 RAM enough to churn out almost full performance from a P4 2.6 Ghz. Second, what extra can a graphics card do to performance in terms of 1) Games, 2) Movies (DVD and VCD) and 3) general usage?. What are the different specifications available, and how much would they cost. I would be extremely thankful to get the answers!!!
