5.25MH seems to be a better estimate on jackpot unless my 3 brands are just all bad at overclocking.  My EVGA FTW cards come overclocked with tdp raised so i'm able to get 5.5 out of those with +10 core and +400 memory, but my MSI Gaming get close and most of my Gigabyte 750Ti's look like they're averaging 5.25.

Could do more but everytime I use normally stable overclocks with ccminer it spits out large hash numbers and stops working again.  Happens on any of my rigs so I know it's not hardware or anything else.  I've seen most people here with that issue as well, but hey if there's a fix I'd love to hear about so I can just leave them at the perfect overclock.
