That's great, but granted all 4 cards are optimized by your scripts, the 
question is if flashbench can tell me which one to pick?

All of them work fine, but I want to spend time with the one that is 
best for "my workload", as suggested by David Christensen earlier in the 
thread.

Maybe flashbench cannot tell me anything about that anyway?

Are there other tools?
