The processor or CPU is the brains of the computer - it does most of the calculations your video games need to run (with the video card carrying out most of the graphics work). With it currently being this sort of an important component, you would instinctually go for the speediest - and most expensive - processor you could find, but there is a better choice to blowing funds on some thing that will be obsolete in a yr: getting a processor that will play tomorrow's video game titles at a reduced price is the sweet spot for any gaming pc.
