Quote from NetTecture:
"... I understand thisis different in the Intel made mobo world - mostly as Intel on board graphics SUCKS (in 10 meter high letters). ATI has decent mobo graphics chips for some time.
It's not a matter of the onboard video quality... it's a matter of whether or not the BIOS will allow you to run 2 video cards and 4 monitors. Seems it should never be a problem... got a video card to fit a slot, should run... but not always the case.
ATI on board chips are "decent" (blue ray decoding capacity and playing 2 year old games)
