Hi, i have an i7 that i am mining quark, it says 78-80 khash x core, it has 8 so its a total of 640 khash right? i dont understand there so, i got in other pc 2 x 7870 hd that give me in total 750 800 khash mining Litecoin, is the same value? maybe is a noob question but if i mine litecoins with my i7 i will do it in 650 khash close to my dual 7870, or i will get only one core velocity that is 80khash.

Thanks
