My Friend is telling me something along the lines of "Your CPU only supports a certain amount of pci thingys and that by adding a network card, it will slow down my graphics card, as it will have to 'share' between to two pci lanes."

I have no idea about any of this stuff.

Does anyone know if adding a network card will actually affect my gpu.
