Simply put: no.
If you have free electricity (and thus free AC to cool them) then GPU offer higher MH/$ which is all that matters.
A couple of exceptions:
a) you have free electricity but it is limited. FPGA would allow more MH/s before hitting you free "cap".
b) you have free electricity but that may change in near future (say <1 year) like a student about to graduate.
c) you have free electricity but a low WAP*. Nearly silent FPGA can operate a much lower WAP than a buzzing, heat puking GPU farm can.

The SI unit would be the SOAS (Significant other acceptance factor) but lets face it Americans are never going to accept metric.

FPGA's really only make sense because of their cost savings over time due to power savings.
If you have fixed rate or "free" power, GPU's are going to be your best bet because Mhash/w doesn't come into the equation for you. The only factor you'd be looking at would be Mhash/$.

I ordered one even though I pay a fixed monthly price for electricity. I don't have the room to keep machines all over the place (my fiance would kill me) and the heat from cards causes problems in the summer. So I'm just running two 6970's in my main PC and then will run one of these.
Just as the title implies, are the singles worth it if you dont have to worry about electricity costs? I know they are very efficient compared to GPUs in terms of mh/w but I have a set cost for electricity where I live sooooo...?
