Could someone help figure out a setup?


Hopefully it's okay to ask for help here

I'm very new to computer audio, but since I work on my computer 11 hours a day minimum, I'd like a system finally. Definitely looking for some deep, loud bass, but not looking to go insane with it. I'm thinking maybe $650 max for everything, but I'm also not sure where to begin, simply because many of the higher end speakers I'm finding don't plug directly into my computer (hence why I am reaching out).

If anything, I'd go with some speakers first and get a sub later with a different savings amount, so if I really HAVE TO go above $650, then I guess I'll have to.

What information would be needed from me to help determine what would be best?

I think you should check out the combination systems at Best Buy or you need to add another zero to that figure. 
+1 twoleftears.  One could purchase the speakers 1st then the sub later. The audioengine one would be a match, however one could also look into the Dayton Audio subs offered by Parts Express. 
In response to ' information ' the post ( set-up ) revolves around
' Speakers ' .
Active and Passive are two general categories for Speakers.
If you do not have an amplifier to drive ( power ) a set of loudspeakers then Active is the category to look into for ideas.
Genelec is a highly regarded manufacturer for Sound Production Gear.
Model 8320A is a two way monitor in the price range specified @ $625.
8331A would represent a considerable step-up in terms of performance and not necessarily a price point.
Placing a Speaker on a stand rather than on a desk surface would be an important distinction for a higher level of performance.

Audio Engine products also would be worth looking into for selection.
