I am looking into building my first pc. I don't know a great deal about every component but I do know the basics. I need something that will run the programs I use for work and the games I play in my off time. I use 3D graphics programs, AutoCAD, Inventor, etc. The games I play consist of COD4, Crysis; high graphics, high action games. If anyone has any suggestions on which direction I should go towards, that would be greatly helpful. Thanks..
