The Inq speculates that it isn't very likely that Intel might attempt to buy NVIDIA now that AMD has acquired ATI.
Well, while it is not impossible it is very highly unlikely and not just because of the antitrust implications. Nvidia would simply cost way too much. ATI was a bargain, and very cheap for what AMD was getting. AMD paid peanuts to get this once great company and if you want to reach for Nvidia you would have to dig much more deeply into your pocket.
You would have to spend at least eight billion dollars to buy the currently-available Nvidia shares. Of course, you have to add some incentive on top of the price so we are talking about close to 10 billion dollars for this green-loving graphics company.
Intel could afford it, of course, but it has to solve some in-house problems first. Ten billion is a fair wedge, but not for a company as big as Intel. However, the US SEC would never approve such a merger anyhow.
