I'm very new to building PC's as I have just stopped console gaming. It seems that the hardest part for me is actually finding the correct parts, especially with my budget. The games I plan to play the most are-Garry's Mod, CSS, Chivalry Medieval Warfare and Deadliest Warrior, Minecraft, and Killing Floor. Here comes the worst part: I need a monitor, mouse, and keyboard. (mouse and keyboard can be as cheap as possible.) I would prefer a monitor above 19 inches. My budget is around $650. (I would prefer if it didn't go over $700.) I need everything.
