The dpi of your output image matters where 'jaggies' are concerned. For posting in the gallery, I usually render my images at 120 dpi. For print quality images, you have to crank that up to 300 dpi which makes for a long render but produces a picture that will look really nice when you print via your own printer or take it to a photo processor for nifty things like t-shirt transfers.
