If your applications remain 32 bit, using the 64 bit fbclient.dll would make them stop working, as 32 bit applications cannot use 64 bit DLLs (and vice versa).

Of course there is: you can use more memory on the server. That is usually the major benefit. Sometimes applications can be (slightly) faster on 64 bit (on the other hand they could also be (slightly) slower), I just don't know if that applies to Firebird.
