Just wanted verify whether it is true as my friends has been suggesting me of this. He said "There is no need to get a graphic cards if you have an i7 processor with 16gb ram" but i though it was nonsense, without a graphic card, how are it is suppose to do the shading and games? i thought he might be speaking a shared graphic card (on board) can be better than dedicated graphic cards. But would it be true? and is it worth it? any thoughts?
