If you need a 64 bit architecture, then I prefer the Alpha Architecture to 
other 64 bit systems.  The EV67, EV68 and EV7 systems price vs performence 
appears reasonable to me, assuming that you really need a 64 bit 
Architecture.  If you do not need a 64 bit system aimed at High Performance 
Technical Computing, then a 32 bit system will probably provide a less 
expensive solution.

The Alpha EV7 CPU will probably be last the alpha chip produced as we know 
it.   I believe the EV7 systems should be out late summer or in the fall.  I 
suspect that these systems will be available until at lease 2005.

When the the Hammer chips / systems are released or the next release of 
Itanium, we will have to wait and see how they compare to Alpha.

Best Regards,
