Indeed. Sounds like in your case the i5 6500 you have is already suiting your needs, so really no need for more expense. For someone who doesn't have something like that already though and needs to make a purchase, I've come around to generally recommending something like the n100 over a used older-generation processor simply because they cost very similar prices, but I feel you get a bit more with the more recent chips due to the modern HW encode/decode and low power use.
