You know that couple that is always at odds with each other, turning parties and other get-togethers into awkward affairs? The worst part is when they both turn to you to pick a side, and all you're trying to do is have a good time. For power users, that couple is Intel and Nvidia. We don't know what it is with these two, but just when their relationship appears to be on an upswing, another squabble breaks out.

After years of butting heads, Intel and Nvidia just recently came to agreement over licensing the GPU maker's SLI technology for use on Intel chipsets, and all appeared to be right in the world. But now the two are at it again, this time with Intel taking the offensive. Intel has filed suit against Nvidia this week claiming that the four-year old chipset license agreement between the two does not cover both its current and any future CPUs with integrated memory controllers.

"Intel has filed suit against Nvidia seeking a declaratory judgment over rights associated with two agreements between the companies," Intel said in a statement. "The suit seeks to have the court declare that Nvidia is not licensed to produce chipsets that are compatible with any Intel processor that has integrated memory controller functionality, such as Intel’s Nehalem microprocessors and that Nvidia has breached the agreement with Intel by falsely claiming that it is licensed. Intel has been in discussions with Nvidia for more than a year attempting to resolve the matter but unfortunately we were unsuccessful. As a result Intel is asking the court to resolve this dispute."

Nvida contends that the license agreement is still valid, however admits that it has been "working with Intel to come to some kind of agreement" for the past year. And despite the lawsuit, Nvidia says it has no plans of changing its roadmap, including those chipsets which extend to future processors.

Not even our divorced parents fight this much.
