i'm just wondering if there is a performance problem with rendering menu and hud using glBegin( quads )? is there a point in using vertex arrays / vbo for menu text and hud? thanks.

It depends. For a few hundreds of quads there should be no problem using immediate mode rendering with glBegin / glEnd. If you have some thousand quads it depends where your application hits its bottleneck then.

But usually this should be no problem and using VA or VBO is overkill in this case.
