oclHashcat-plus will support up to 128 GPU with next release. you can cluster them using VCL, but that works only on Linux. crossfire should stay disabled when it comes to cracking. Both oclHashcat-* programs have specially designed workload distributors that no generic solution can do better. I think it was blandyuk who made some comparisons on crossfire here on this forum.
