Hello, I'am going to be building my first computer in the coming months ahead, (I expect the holiday season to drive prices down).
What I really need right now is an build that can handle college work and HEAVY video encoding and in the future, gaming. My 5 year old 1.6ghz AMD cpu simply cannot do the job at a satisfactory rate anymore and with 4k video on the horizon I simply need more horsepower.
I included a CPU cooler so you can overclock your CPU. The RAM I chose is faster and only $2 more. The Corsair case is a much better quality case with great cooling and cable management. Your PSU was overkill unless you want to Crossfire/SLI and the one I selected is plenty of power for high overclocking and also Gold rated for better efficiency. the build total is only $3 less even with the CPU cooler.
Looks like you have a great start to a nice editing build. Good luck!
