I have a GeForce MX400 128MB PCI video card and I just got a new motherboard which has the NVIDIA? GeForce? 7050 / nForce? 610i Chipset. Should I junk this old GPU for the onboard till I can get a new video card? I ask because I can’t get the ethernet working on my new motherboard (Gigabyte GA-73VM-S2) and I want to put in a separate ethernet card, and my motherboard only has 2 pci slots, 1 being used up by extra USB ports, 1 by the video card. So which is a better choice for my video?
