So, does this seem correct for one 750ti?:
-X11:2.6MH/s
-Jackpot:5.5MH/s
-NIST5: 8.4MH/s
-Quark: 4.7MH/s
-Groestl: 8MH/s (!!!!!! was 3.1MH/s before !!!!!)
I used these numbers to generate following list for one 750ti:

Again, this list is only a snapshot for this moment, with current prices and difficulties, so lower your own estimates.
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.
Hah, yeah, should've taken the overclock down. Anyways, ratio's are shifting, as you can see

GRS is becoming 'interesting' again
I get such a freak-out only when it's too hot where my rig is ^^" Else +60core, +200mem, +31mV works fine for me (one EVGA SC and one Gigabyte)
