Looks pretty good. My main suggestion would be that if you can afford it, consider going with a ~250 GB SSD for your main drive, and then a cheaper 2TB or so HDD for bulk file storage. A computer running off an SSD feels amazingly faster. It would add about $200 to your overall build cost.
My other suggestion would be that if you're just using 8GB of memory, get a single 8GB chip rather than 2x4GB. There really isn't a performance or price difference, and you leave the door open to more upgrades down the road. One minor point would be that you could get away with a 450-500 watt power supply if you want, but 650 is fine too, if you're looking for the ability to pop a GTX 980 Ti or some SLI 960's or 970's in there down the road, or whatever.
