Intel to purchase nVidia?

As we all have seen, ATI has been bought over by AMD. While all these is going on, many have asked what are Intel's reactions to all these things taking place. Well today a rumour has spreaded that Intel might be courting Nvidia into purchasing it.

Rumours of this has shot the nVidia's stock up slightly and some sources claim that there will be an announcement made tonight about the plan to buy over the industry giant, Nvidia.

It is odd as nVidia is very expensive, about USD 10 billion, while Intel already has a thriving graphics section, something which AMD did not have before the ATI acquisition. There are, of course, issues of prestige and the need to be associated with a high-tech graphics company but this would seem more like tit for tat rather than a sound business move, unless Intel has some other plans which may need nVidia expertise, such as developing in-game physics, unified shader architecture etc.
