I tried mining on my i7-4750 which is the same as the 4770 just at a lower clock speed, I'm getting 45KH/s per thread on 8 threads for 360KH/s total.
There's no way that those speeds are real.
after searching what minerd instructions best fit for my i7 3770k
found that minerd-avx-aes-sse2-sss3.exe bringing me 60kh/s per thread

i cant use rest 2 threads, they are reserved for those gpu's that are using them!
Another problem guys, last night i noticed that when i set 2 x 280x to mine, my cpu goes to 50% load... if i turn one card only 25% CPU load... so from this i can say that one card is taking my 25% of CPU no matter how many cores i disable or enable... if i enable only 1 core 2threads my cpu is like 99% with sgminer!
on other hand my older gpu's mining using only 1% of CPU!
can anyone figure out this? i would like to turn those 2 threads into 120kh/s
