For future proofing your computing platform , I would go with a 64 bit system. You will not regret it. All crystallography applications live very happily on a 64bit platform .
There were a few teething troubles , but nothing an email to ccp4bb , phenixbb , coot or pymol newsgroups cant fix. We recently upgraded all our computers to 64bit Here we use two Mac Pros running Leopard OSX -64bit , after a few teething problems we are at equilibrium. Our third machine is a 64bit dual - quad- core , 16GB workstation from Appro Linux with a nvidia graphics card that they installed for us during the build and it does stereo ( Quadro 3450 bought from ebay for $250 OR Quadro 4600 newer version for a whole lot more $2300-major overkill) . It runs Ubuntu Hardy-Heron 64 bit , installed from downloaded iso image and almost minimal tweaking. Since most projects release builds for ubuntu , I am partial to Ubuntu . But Gentoo is also a great distribution.
