hi i am planing to build a new pc. this will be my first time and i am a beginner and know very little exept for some basic things. i have no idea what parts to buy and would appreciate if you could make some sugestions. i want to do the build for under 500. i would like to be able to play battlefeild 3 and newer games coming in the next couple years. i would like to use intel processors instead of amd but if amd is cheaper that will be fine.
