Many people underestimate the value of vectors and continuously seeking free psds for their designs. However, vectors are a lot more flexible, easy to use, resizable and can b often broken to make sub-vectors which gives additional flexibility to your designs and ideas. We put together a list of website that offer absolutely free, yet high quality, original and useful vectors for download. Check these websites out, though you might noticed that some free and open source vectors are offered on several sites, yet most of them do offer a great deal of unique designs, so I recommend to have them all bookmarked if you are repeatedly looking for new graphics and inspiration.
