The problem is your 200Mhz R4400 is only slightly faster than one SM71 which is a SuperSparc II running at 75Mhz. My Sparc 20 with Dual SM71's feels slow at times, mainly when doing web browsing or software compiles.

I'd love to have an SGI box, but they're even more expensive than Sun's or DEC Alpha's. An even bigger problem for me is you can have a x86 box running Solaris 8 that will totally blow away any moderatly fast SGI or Sparc system and will likely cost a lot less. My Dual 400Mhz Celeron running Linux pretty blows away any of my other systems with the possible exception of my Mac, and my DEC PWS 433au.
