I currently run a machine that allows me to program in OpenGL 2.1. If I were to make a program, should I use the power of the current OpenGL versions like 3.x/4.x or use 2.1?
On a side question: How can I tell what's the highest version of OpenGL my computer can run?
On another side question: does only upgrading my video card allow me to program in upgraded versions of OpenGL?

I answer for the above question. I come across to the tool below, it's really complete in itself and let me see all OpenGL version that my system currently support (from 1.0 up to what it actually support). As well for extensions available for my system to use. Not only for ARB though, it ranges from NV, ATI, OES, etc.
