One major problem with adding a faster CPU to an SGI is the MIPS chip itself---code compiled for one MIPS CPU (say, the R3000) won't run on another MIPS CPU (say, the R4400) due to the differences in the pipeline. MIPS compilers were specific for a chip because such details were not hidden in the CPU itself, but left to the compiler to deal with. -spc (Who had near exclusive use of an SGI in college in the early 90s)
