Will my custom PC work?

I'm building a custom PC. Casual to Gaming focused. Would like to spend less than $1000 but $1200 is absolute limit.

Problem is, I'm an idiot. I can't even call my self a layman of custom building. I understand the different parts and what they do for a PC, but I don't know what goes with what. Your mission, should you choose to accept it, is to tell me if what I've got so far works. If it doesn't, or if you a better part (at a reasonable cost please), feel free to add it. Ready? BTW all prices from amazon.


Motherboard: GIGABYTE GA-880GA-UD3H AM3 AMD 880G HDMI SATA 6Gb/s USB 3.0 ATX AMD Motherboard -$130

Memory: Corsair XMS3 4 GB 1333MHz PC3-10666 240-pin DDR3 Memory Kit for Intel Core i3 i5 i7 and AMD CMX4GX3M1A1333C​9 - $23

PS: Lifetime Series Pro 750W Psu - $85

Sound Card: ASUS PCI 5.1 Channel Sound Card XONAR_DG - $27


So far, I think I'm pretty good. Here's where I'm not so sure:


Processor: AMD FX-8120 8-Core Black Edition Processor Socket AM3+ - FD8120FRGUBOX - $155

Hard Drive:Western Digital WD Scorpio Black 750 GB SATA 3 GB/s 7200 RPM 16 MB Cache Internal Bulk/OEM 2.5-Inch Mobile Hard Drive - $95



I'm at a little below 700   but I still need a graphics card, and a case. I won't spend money on a driver yet, and I already have a copy of windows xp but I may purchase windows 7 home edition. Will worry about that once I think I have my parts...

What I need is a graphics card (may also purchase a second one for CrossFiring, but I'll worry about that later too), a case, and a... wait I think that's it!   maybe a

Cooling System: Noctua 6 Dual Heatpipe with 140mm/120mm Dual SSO Bearing Fans CPU Cooler NH-D14 - Retail - $80


What I would like to know is if the parts I've mentioned so far are compatiable with each other. This might seem obvious to you, but I'm incompetent  

If something doesn't work, please offer alternatives with comparable power and price. And I also need a graphics card that costs less than 200 dollars. I would appreciate any help even if it's that I should go into a local computer shop or something. Main reason I wanna custom build is because after several desktops and laptops, I've learned that I'm paying alot just for the brand. That's probably way I don't wanna go to one of those websites that custom builds it for you, because my computer would then be "branded".
