or does OpenGL 4.X support the same features as DX11 ?

Yes, and yes. Except Compute Shaders - but for that you can use OpenCL.
OpenGL 4.1 core has about the same features as Direct3D11. There's even no need for extensions.

wow, thats pretty good!
so if try out OpenGL 4.X, i wont need to worry about weather certain extenstions are present ?
is OpenGL 4 only supported on new Graphics Cards, or older ones as well(3-4 years) ?

yes the opengl 4.1 core feature set contains the directx 11 feature set.
no, opengl 4 is only supported on nvidia 4xx and ati 5xxx or better. That is with a directx 10 capable video card you can't get directx 11 features (because of hardware limitations). To add directx 10 capable video cards are going to only support opengl 3.3
