My problem here is that Intel is getting into the GPU market at all. They already have a dominating share of the CPU market, and my fear is that Intel could write out support for GPU's other than their own on their platforms chipsets.
It wouldn't happen initially, no if Intel did that they'd be attacked from all sides. Instead Intel may try and slowly leverage out the other chip makers in the business. AMD and ATI are two sides of the same coin, so they can continue to compete, but they are already on the ropes from the stiff competition from Intel and Nvidia. Once Nvidia chips can only run on AMD platforms, its short work for Intel to push AMD off the map too.
Something needs to happen here. Intel already has the ability (although they haven't exercised it) to become a true monopoly, the reason they haven't took the steps to see AMD immediately goes out of business is because if they did they fear regulatory response. But just because they are taking a slower route to pushing all other chipmakers out of the market doesn't mean they aren't trying to push other chipmakers out of the market.
I'm glad that Intel has provided such good, low cost components in recent history, but that can change the moment AMD closes its doors. The near future is bright, with more competition leading to better prices and performance, but the future of 5 to ten years from no is getting dark.
