Explanation
The board, CPU, and CPU cooler will allow you to overclock very significantly. The i7 will already help with rendering, and the overclock will give it even more of a boost.
The GPU will be amazing for gaming, and I would suggest you overclock it as well with MSI Afterburner to get the core clock up to at least 1000mhz, but I would push it even higher than that in order to get the most performance possible out of it.
Use the SSD as a boot drive and the HDD for storage. If you wanted to though, you might actually be able to create a 64GB partition on the SSD and use that as a cache for the hard drive. Then you could use your hard drive and that partition as a boot drive, so that your most used programs utilize that part of the SSD. Then you could use the rest of the space on the SSD to install whatever you want to run faster. It would probably just be better to manually install the programs you think you will use the most on the SSD though. Either way the choice is up to you.
The power supply has enough power and cables to hook up another 7970 later down the road if you ever wanted to. Not to mention it's modular and has a single 12V rail, which will make it extremely easy to work with.
The case is a very nice mid tower modeled after the HAF X. It will have great cable management and airflow. You can always get a different case if you don't like it.
RAM is cheap, so why not get 16GB?
