If a 4D25 is your price range, try to get enough for the 4D35 instead.
It's not much more expensive, once you start pushing the sales folks.
The floating point performance is significantly better.

that programmers write for is higher. The problem with porting code is
1) graphics calls
2) Unix (variant) calls
Irises use the Silicon Graphics Library calls, ESV uses PEX (Phigs under X).
PEX is a public standard, so it may win in the (very) long haul.
SG has a huge head start, so things get written for it first,
kes the guts of the EVS? This would be important, for assessing

The internal architraries would really make things easy, but the relatively small
quantity of stuff ported from SG to RS6000 suggests that reason 2)
above may be involved. (I have no personal experience porting
between this machines).
Finally be aware that SG will then ported to other stuff. (including IBM RS6000).
Many of us thought that the fact that IBM licensed SG's graphics
lib it up).
BTW the ESV uses MIPS chips.
