I agree with undeath (like always ?) ... and would like to suggest that depending on how small your word lists are etc, you could also think of an alternative like this:
1. first precompute and store a modified 2nd word list: combine the second word list word2 with the digits already combined
2. run -a 1 with word1 and word2_combined_with_3_digits
you could for instance use "hashcat --stdout -a 6 -o word2_combined_with_3_digits word2 ?d?d?d" to combine the dictionary file word2 with 3 digits.
Of course an approach like this only makes sense if:
1. the word list word2 is not too huge (but a too huge word list would anyways be a problem of infeasibility for -a 1 attacks)
2. the storage is not too much of a problem (fast I/O) etc
3. the resulting speed is acceptable
The speed of course depends also a lot on your GPU/CPU setup and most importantly on the hash mode (in your case it is -m 2500 = WPA/WPA2).
A small advantage of this pre-computation approach is that the ETA would be more accurate and the status display of hashcat will show more info (because no pipe is involved in this case).... but of course for most users the speed is more important than just some displayed values.
