I'm currently in the process of building my first PC from scratch. I've taken apart the computer that I have now and put it back together a few times so I know where everything goes. My knowledge about the parts are still a little bit iffy so if you guys can offer me some advice on them that would be super. What are you going to use the PC for? This PC will be mainly used for gaming as I have a laptop to do all of my school work with. How much is your budget? I'm trying to aim for below $1500 if possible but will go $50-$100 above. Where are you located? (a.k.a. fill out your profile) US Are you willing to buy online? I was hoping to buy everything online as there are no good computer parts store near where I live. Are you going to re-use any parts from an earlier build? Nope Do you need other peripherals like a monitor, keyboard and mouse, among others? Nope Have you already bought any parts? Not yet, I want to buy it all at once so I can put it together immediately. Do you have an Operating System (OS)? My cousin bought a Vista Home Premium 64-bit OS a while back that he's never used so I'm taking it. Will you need any aftermarket cooling, such as a CPU\GPU cooler or a watercooling setup?

COOLER MASTER V8 RR-UV8-XBU1-GP 120mm Rifle CPU Cooler From what I read the stock cooler for the i7 920 kind of sucks so I included this. Any advice or critics would be really useful. Thanks in advance.
