I'm building my first computer for gaming, and I'm really excited to get this project all together because right now, as it's on paper it's looking really good. My budget is to be determined (right now, 800-1200 USD) because I can earn the money pretty quickly and I'm willing to wait if I have to on this.
I've been looking to the forums on Tom's Hardware for help on certain pieces and while I haven't made any posts myself, the other members have helped me learn a lot.
I do need help checking the compatibility of all my parts (and if I have them all). If you think that there's anything that needs changing or if I need to add anything to further enhance my gaming computer, please say so!

And with gaming, you probably should invest more in the graphics card, the gains from an i5 -> i7 isn't worth it if its jsut gaming. Just a thought. You probablly could get a much better graphics card.
I always recommend new builders start with a cheapie practice build before they spend serious money on a big build. You would be surprised how much you learn doing one. It's certainly not a necessity, but I think you would find it beneficial.
