hi, i bought a new gaming pc for my son, i am not very knowledgeable here on the latest gear, it has the AMD ryzen 78003D which runs the onboard radeon graphics, but the pc also came with the Zotac geforce rtx 4070 ti super graphics card, this RTX card added $1300 to the cost of the pc, now i realize the pc already had the onboard radeon graphics and i wonder why did it need the geforce rtx card, reason i ask is the pc is new and after starting up i find the geforce card is not working, the pc is running off the Radeon graphcs which are fine and my son has noticed no issues, so was the geforce card a waste of money ?
