Vista 32 vs 64 bit

can anyone tell me the differnce b/w windows vista 32bit and vista64bit...i just installed 64bit ultimate edition....plz tell me the difference

according to me 32 less colors and loose graphics, 64 best vivid colors and strong graphics you can see even one single pixel clearly and it also best for wide screen monitors

More or less the same thing has been discussed before.
