Need help with first computer build

[MoCal8]

Hey everyone. This is going to be my first computer build. I'm replacing my computer that's about 5 years old, so nothing is really reusable. I pretty much saw a build on another post that I believe would do the job, but I'm not sure if it is overkill or not enough.

Budget: $1600
Resolution: 1920 x 1080
Games / Settings Desired: I usually just play WoW, SC2, and Diablo 3. Ideally I would like to play all on max settings.
Any other intensive software or special things you do: Nope
Country: USA - I'm near a Microcenter if that can factor into getting parts cheaper
Parts that can be reused: None
Do you need an OS?: Yes - Are students able to get copies of Windows 7 for less than retail? I have a friend who is still in college.
Do you need peripherals? I would welcome keyboard and speaker suggestions

It's my first time posting, so I can't give a link to the build. Here are the parts that I plan on using. Thanks in advance for any advice!

CPU: Intel Core i5-3570K 3.4GHz Quad-Core Processor ($189.99 at Microcenter)
CPU Cooler: Arctic Cooling ACFZ13-PRO 49.7 CFM Fluid Dynamic Bearing CPU Cooler ($35.72 at NCIX US)
Motherboard: ASRock Z77 Extreme4 ATX LGA1155 Motherboard ($132.86 at Newegg)
Memory: Mushkin Blackline 8GB (2 x 4GB) DDR3-1600 Memory ($48.99 at Newegg)

Storage: Crucial M4 128GB 2.5" Solid State Disk ($106.31 at Amazon)
Video Card: Asus Radeon HD 7950 3GB Video Card ($407.86 at Newegg)
Case: Fractal Design Arc Midi Tower ATX Mid Tower Case ($69.99 at Newegg)
Power Supply: SeaSonic 520W ATX12V / EPS12V Power Supply ($69.64 at Newegg)

I would get a bigger power supply. 520 is cutting is pretty thing with the video card.

it might be worth a little extra to get a 256gb SSD over the 128. But thats just me.

You can get the mobo/cpu bundle at microcenter (50$ off the purchase). You can also get an evga gtx 670 ftw instead of 7950 (409.99 on newegg).

It's not coming anywhere close. 7950 has a max TDP of 180w, his processor 77.

OP, your PSU selection is fine.

GIGABYTE GTX 670 Windforce - $400 (one of the better 670's out there)

Better card overall and cheaper even if it's only by a little

Performance comparison: Stock 670 vs stock 7950

The CPU heat sink isn't really any good (better than stock though). If you need to keep the price low look at something like the Xigmatek Gaia instead.

Rest of the build is really solid.

Agreed with the GTX670, I would take it over an HD7950 any day. Especially if you're paying $400+ for a 7950.
