Maximum PC

Yea right, not by far...I'm a total novice. But since you're here now, I'd love it if you can tell me where I could improve this build for gaming.

I have peripherals (recycling). I do not plan on overclocking.

Also, where will the bottleneck of this system be?

Components:
CPU--: Intel Core i5-3570K
GPU--: EVGA SuperClocked GeForce GTX 660 2GB 192-bit GDDR5 PCI Express 3.0 x16
MoBo-: ASRock H77 Pro4
RAM--: G.SKILL Sniper 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
HD---: Western Digital WD Blue WD5000AAKX 500GB
PSU--: SeaSonic S12II 520 Bronze 520W ATX12V
Case-: Rosewill CHALLENGER Black Gaming ATX Mid Tower

~$735.
I'd like to keep it under $800 since I have to purchase Windows 7.

MUCH APPRECIATED ALL, THANK YOU!

The only real glaring problem I can see is the motherboard OR CPU. You chose a K-series CPU, but an H-series chipset. In order to overclock the K chip, you need a Z77 motherboard. If you don't plan on overclocking, just get the 3570 "non K" chip. If you do plan on overclocking, get a Z77 motherboard. It seems the Z77 & H77 aren't that far from each other cost wise...

^ I concur.

Imho, get the "K" CPU and Z77 mobo. The difference in price is marginal and even if you don't plan on overclocking, the fact that you are able is worth the extra $20 or so.

I would also suggest a bigger HDD simply because it's cost-effective: as of now, 1 TB ~$70 while 1.5 TB ~$80 and 2 TB ~$100.

Otherwise, overall solid build imho.

An SSD will be a huge improvement to your rig.

If you're planning on getting a 500GB hard drive anyway, I'd suggest you swap it out for a 128-256 GB Crucial M4 SSD. The difference is amazing, easily my most recommended upgrade. If you find yourself needing more space later on, hard drive prices will have dropped to reasonable levels.
