Are we all forgetting that Silicon Graphics DID make a run at WIntel-based PC's?
They were technically, for the most part, very sound designs.
They used good old-fashioned quality engineering which, unfortunately, required some expensive components and significant R&D overhead.
With all they did right in their efforts to mass-produce the most kickass and desireable PC workstation in the world, the 320 and 540 Visual Workstations still only rated as an "OK" value with most pro's.
Their "Cobalt" 3D hardware Pipeline was only barely able to keep up with the newly-killer NVIDIA and venerable Wildcat boards, and DirectX implimentation was non-existent (gaming suffered a bit on these boxes)
ands fell further behind in the price/performance arena quickly...
Using NVidia chips after that was the only move they could have made -there was no time or resources to engineer a completely new 3D hardware pipeline for WINNT -heck, they still havn't done it.....
-but, ultimately, it was NVIDIA (and to a lesser extent, the OTS (off the shelf) PC performance explosion) that did the most to put SGI's PC's out of business.......
I'm, glad they pulled-out .....gracefully as they did.
