Master Collection of Resources

If you want to find resources, the first source you should use is [You must be registered and logged in to see this link.] This is pretty generic and obvious but honestly, Google isn't as bad as I thought.

Please keep in mind that these are the resources that I have used and they are quite reliable and I haven't had a problem yet. If you have something to add to this list, feel free to share them.

Renders
[You must be registered and logged in to see this link.] - This is my favourite site to get renders. It has a large collection and a very large variety. Downside is, it's in french.
[You must be registered and logged in to see this link.] - Another good website for renders. Not as good as renders-graphiques because of the much smaller collection. Downside is, you need an account to be able to download renders.

And this is pretty much all you need to search for renders. Or at least I didn't have any trouble.

Textures/stocks
[You must be registered and logged in to see this link.] - Don't worry, they'll never know! This is a good place to get textures but they're kind of hard to find, and remember to ask permission before using!
[You must be registered and logged in to see this link.] - Well, before stock garage got merged, it wasn't confusing as hell. But this site has stocks and textures of all kinds including abstract effects, people, and architecture.

Brushes
[You must be registered and logged in to see this link.] - I mostly use this site (although I barely use brushes anymore). Not much to say about this.

Fonts
[You must be registered and logged in to see this link.] - Afaik, dafont has all the fonts you will possibly need. I also don't believe you need a lot of fonts because simple fonts often look better in gfx work. Some of the fonts I use are: Luna Bar, Jellyka, Levi Brush, and Champagne and Limousines.
