Sorry to break the bad news to you, but Intel just bought the Alpha
production business from DEC, so it looks like they are gonna kill it. 
And WRT the K6, on certain instructions its FPU is faster than a
Pentium, and on others it's slightly slower.  Differences are
negligable, Except for programs optimized specifically for the Pentium
FPU.  Quake is the only one shipping today that anyone knows of, and
from the amount of problems Id is having maintaining multiple versions
to run on Intel vs Non-Intel chips, probably the last, too.
