My opinion is to first determine a few issues.
How much RAM will it need? If over 3GB of physical RAM, consider 64 bit. Are there third party applications you need to run on it? If they are 64 bit, that answers the question too. If 32 bit, are they supported on 64 bit OS? Do they have different versions for 32 and 64 bit?
lots of good info to ponder back from those that responded.
what i a getting at is, why would one use x86 64 bit Centos version 4.7 when one can get the same in x86 64bit Centos 5.2 or later version?
is there a reason to stay with the older version other than for specific deprecated hardware issues or something else?
is 64 bit Centos 5 just plain better OR would some of you choose 4.7 over 5.x and why?
