NVIDIA and SGI Align

Alowishus writes "Another nail in 3Dfx's coffin? NVIDIA and SGI team up - as a result, SGI drops their pending patent infringement suit and both companies swap patent portfolios. Press release is here. " I'm not really sure what to think of this - I can't see SGI giving technology to nVidia that would let us x86 users all have the same cards as their users...Is it just a way to get rid of the lawsuit? Maybe NVIDIA's manufacturing capabilities?
