Beginner Gaming PC Help

No budget?

My budget is absolutely no more than $670. Not including a monitor, hard drive, keyboard or mouse because I already have those.

Thank you for the confirmation prince

Your components are all compatable. You didnt list prices so I'm not sure what you are paying for the graphics card, but if its in your budget here is a great price on a gtx570, which the psu you picked will run:
