Building PC soon, is this good?

So, I have been wanting to make my own gaming computer for some time, and I have found some parts that seem to be pretty good judging on customer reviews. I plan on playing games such as Skyrim, Word of Warcraft, and games that are big and need good performance. I was wondering if this set up would do me any good, or if I should upgrade somethings before I go on a buy the pats.

Processor: Core i5 3570K 3.4GHz LGA 1155

Motherboard: Z77 Extreme4 LGA 1155 Z77

RAM: Ballistix Sport 8GB DDR3-1600

GPU: NVIDIA GeForce GTX 660 Ti Superclocked Edition 2048MB GDDR5 PCIe 3.0

Case: V3 Black Edition ATX Mid Tower Computer Case

Power Supply: TR-700 TR2 700 Watt ATX Power Supply

SSD: Extreme SDSSDX-120G-G25 120GB SATA 6.0Gb/s 2.5" Internal Solid State Drive

HDD: Barracuda 2TB 7,200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive STBD2000101

Also, I plan on doing some editing and rendering, but I will use this PC for mostly gaming.

Thanks!
