previously i had intel D945 board in which 128MB video card was built in. Now i have gateway e4300 motherboard. does it have inbuilt video card or not..... because many games which i was able to run previously on intel d945 board don't run on this board..... or it is driver issues
If you are only using the IGP on the mobo, then it is normal for you to experience slower performance after you change the mobo. You old mobo has Intel 945 chipset (GMA950) and the replacement mobo is Intel 915 (GMA900) for IGP. Both mobo IGP is crap for game and I recommend you get a dedicated GPU if the mobo has PCIe and you have a decent PSU.
