well the z77 features wont be utilized since you have a SB. personally I would get a gtx 670 and evga just released the 4gb models so you wont have to worry about future bottleneck. Btw how much are you editing? A very good editing build uses 16gb ram and a quad core with hyperthreading

I'll be editing movies and film skits, nothing too heavy. Yeah the gtx 670 seems like the way to go, thanks.

Do you need an OS? You didn't include one in your build, but you said you only have a monitor and a mouse.

Woops, forgot to mention I have windows 7.
