I might be of some help to you. I went through the Dell learning curve and what I came up with has helped me . I went to Fry electronics and had a tower built per my specifications and it saved me a lot of money! And I received good quality components. Dell puts in some good things and then athrow in some junk. I run a 850 Watt tower with a 10,000 RPM C Dr. and to 7400 RPM drives. I run a GeForce GTX 670 graphics card and AI seven quad core processor with 12 gigs of RAM. I also run premiere Pro cc and all of the Adobe products using their cloud applications. When the dust settled on this project if memory serves I had around $1500 invested. The same machine. I've read about runs around $4000. And this machine runs premiere Pro and Photoshop and other applications simultaneously. Good luck, I'll never buy a production machine again not for such heavy lifting as video editing
