that's what I was saying yesterday, the mining review is usually strange...
X11 seems rather okay compared to my 780ti around 6MH/s (scrypt... might be a bit underestimated...)
Whirlpool... either I forgot to update my github and I did a really really good job at optimizing   (might be true though... but not that much... beginning of last week, I had 50% of whirlcoin net hashrate  ), but the 780ti does around 18MH/s so the 12MH/s looks small...
Now there is huge bottleneck for the 750ti, but it should be at least 15MH/s (if it scales properly....)

might still buy 2 for sli...
