Intel's final answer to the AMD/ATI merger is still in the works, though they have been providing some interesting tidbits. It seems that they are working with nVidia to potentially develop SLI-supporting Intel chipsets. This is a big change of heart for nVidia, which is very stubborn about letting anything other than an nForce chipset work with SLI. It's a change, though, that many will welcome, as Intel's chipsets tend to be the most common in Pentium-supporting motherboards. The original article was very sparse on details, leaving much to the imagination. However, we're supposed to hear from nVidia quite soon to confirm this.
Not only would a deal of this nature make a lot of business sense for both Intel and nVidia, it is one that would allow nVidia to greatly increase marketing and propagation of SLI.
