I would never buy a motherboard with built in graphics unless it also have a way to put a graphics card in at a later date.
My sister-in-law have a Dell with built in graphics and even on simple things like DTP, it struggles when there are a load of graphics. the only thing that machine is good for is surfing the net and emailing and only just at that.
Always, always get a computer that the video card can be updated.
