Building my first Core i7 PC

My company is allowing me to build a new PC. It’s a design and programming job for a video processing website. Of course, I won’t be allowed to play games at work, so I only want a low end GPU. It’s my first i7 build, so I’m asking you guys whether everything will work out.
