JamesSneed :
This is a little backwards having people list potential uses for your workstation. Why don't you just state what this will be used for even if you don't know specific applications.
If you want a list go to Anandtech's bench and see the various things they test:

Sorry I didn't list them, guess that was kind of stupid. I will be doing heavy multitasking, downloading 4k+ videos/pictures and probably dealing with a lot of things in over 4k, not to mention the other programs (simple programs, but lots of them) like word, etc, open at the same time. I'm thinking I don't need a GPU, however if I did get one where would I benefit or would I not benefit at all if I am not using lightroom or 3d modeling software?
