Memory and CPU will have virtually no impact on the cracking part. For sorting large wordlist, memory will help but you can always do the attack preparation like wordlist sorting, removing dupes or other on another machine and use them on your cracker.
Man, forget about rainbow tables. They are obsolete. The only place they could be useful is for LM hashes but not in your case. With your rig, you will go in the 1-7 all keyspace in a very short time.
mastercrack,
Thank you very much for your fast replay.
Let me try make myself more clear.
1) 9970 will be released soon, so, instead of buy 8x 7970 I will buy 8x 9970 (Single GPU);
2) I still waiting information about 8x 6990, but I do not have any news about it; I know you can have 8x S10000 (16 GPU);
3) Will be 8 GPU running -a 3 -i "x14" (?d) faster than RT? I really do not know, but, I guess you are right.
4) I prefer build one computer to do "everything" (attack preparation + the attack itself) in the same machine; Do you see any negative point here?
Thank you very much for your help and attention, and, again, sorry for my bad english.
