Yeah, who cares about 64-bit...nobody really needs one. And those web servers will run just fine on 32-bit CPU\'s when they have tons of RAM and HDD installed.
What 64-bit likely to do for you is:
(1) Create problems due to do instablity becoz it\'s still new.
(2) Software incompatibility.
(3) Hardware incompatibility.
(4) Slow down ur current rig because 64-bit CPU EATS RAM like breakfast. Yes, a 64 bit CPU will require the double amount of memory in each register.
But lhey, look at the bright side. You\'ll be the only person within a 10,000km radius that\'s probably facing all these problem and owns the exclusive bragging rights to it!!! LOL.
