Due to the lack of experience with different computers, I cannot say something about your computer. I think, PD16 will run on that machine, but the point is, what do you want to produce?
ColorDirector is not part of PowerDirector. It is a seperate program. And it is not the answer to upscaling (ColorDirector scales nothing, It's good for color grading), enhancing (yes, ColorDirector can enhance colors) and producing (ColorDirector is not for producing but for color grading).
Have a good week.
