My GTX died and now im using integrated INTEL GMA 3100 how come that my pc works faster with gma than it did with GTX ?

Your gtx was most likely run fown and so the ghz had been slowly dropping until it died, therefore your intel graphics would seem better

What GTX type is it, dude?

I`m not sure, but there is almost no way of Intel 3100 can win against any GTX when it comes to GAMING

performances.

Since the gpu has fail there is less of a power draw on the pc , intergrated gpu doesn't draw that much power
