The video card is practically unimportant. you'd be better off with cheaper card, and a second monitor, rather than buying a top of the range ati or nvidia card. For video editing, a ti4200 will do everything a brand spanking new card will do |
Not wholly true. Some video editing software can actually utilise the GPU providing you with RT effects without them having to render, as well as improved rendering performance for those effects which cannot be done in RT. Pinnacle's Liquid Edition benefits from a faster video card and also supports the PCI Express cards too (I am sure there are other suites too but I don't know about them).
A 74GB HDD is on the small side if it is the drive which will be holding your video editing projects, render files and captured media. However, it's plenty large enough for an operating system only drive.
