I have Dell Vostro 3546 Ram 4GB, Intel i3 4th Gen.
Now My question is can i upgrade my graphic card to Nvidia graphic card as i have intel HD graphic Card if yes which graphic card is supported by this laptop. if no then why.......
You would need to replace three things:
1. The system board (mainboard) -- the GPU is soldered to it, so the only way to upgrade is to replace the board.
2. The heatsink assembly -- the one for Intel video won't fit the nVidia board and vice-versa.
3. If the system now has a 65W or smaller capacity power supply, you'll need a new one of 90W or better.
