Not only would they keep the money inhouse for Xbox GPUs but could also have the ability to make cards tailored to the newest DX features.
On the CPU side they would have to restart from scratch, but that is the whole reason AMD stock is selling in the sub $10 garbage bin in the first place. If they could get even a slightly inferior CPU out, MS would have far more clout to force retail computer vendors to offer the chip in many configurations.
If MS had the ability for CPU/GPU research and development in-house, there would seem to be more innovation possible as MS would not only be producing items to beat the competitor, but also to make their own software (i.e. Vista) more appealing.
