I recently test rode some FX'es both with and without carbon forks, and without doubt I'm going carbon: the difference in ride quality is dramatic.
I'm now just waiting for my favorite LBS to get a 7.4 in my size in stock, and that may not happen for another 7 weeks or so.
And by the way, the 7.4 FX Disc does NOT have a carbon fork, and I test rode that too, and it felt more like a 7.3: heavier and a harsher ride than the plain 7.4.
