im for gaming so this is correct .
Not sure what you mean.
For games with low CPU requirement and high graphic content the 560 OC and 2100 are a great combo.
For video editing the 2100 will strongly limit you although over time the video editing software will make more and more use of your 560.
Post what you intend to do and what you want people to help you with. If it's a system balance question spend some time saying what you do. For me, more money in CPU and less in GPU would be the right balance, but for a 100% gaming system you may have it right. I'd also go black not blue for the disk. boot time and level load time. PSU look good.
