The actual configuration really depends on a number of factors. Some are Personal Preference, Budget, and Motherboard Requirements.

I recommend Crucial Ram as I have always had good luck with that brand and they have a good warranty as well.

RAM speed also plays a part in this as well. I like to spread the RAM out so my first thought would be to get (4) 8GB sticks. However if you get a faster speed RAM the (2) 16GB works as well. Think of RAM like a highway, the more "Lanes" you have the more traffic can go through. Spreading the RAM  over all 4 channels may give you a little better performance than 2 sticks.

I'm going to be using my pc for editing sound and video files.
And I'm unemployed and using credit cards to buy the memory.  I don't mind spending extra but I really want it to be worth the extra money.
the fewer modules you get is usually the better option, as in that case the memory bus is less likely to cause interference with the modules (ECC RAM would counter that problem). So I suggest getting 2 16GB Modules, provided you get some that are compatible with your PC.

Here is the PDF describing my Dell XPS 8700 desktop.
If you tell me where to locate it, I can get you motherboard information.

You have no choice but to buy 8GB modules.   The specifications for the PC show it doesn't support larger modules.

It also does not have ECC support ... so you need standard unbuffered DDR3 modules.

Can you tell me about voltages?  What are the consequences/advantages to using various voltages?  (See graphic).
Gary CaseRetiredCommented:
The standard DDR3 voltage is 1.5v, but many systems can use the lower-voltage 1.35v modules, which will run a bit cooler and consume less power.      Either choice is fine.
