best drivers for dual AMD 6970
What is the best drivers for oclHashcat (lite, plus and regular)? I noticed a big performance change since last time i ran hashcat on MD5. I am currently running at around 5,5B hashes/second and i think i had somewhere around 3,2B hashes/second last time i cracked alot (a few months ago).

Also, is there any performance difference between different scenarios on different versions of oclHashcat? i.e. has there been any performance increase in 5 hashtypes at cost of one hashtype?
