i don't want to use my cpu i already looked that up that cpu is useless for mining right now ,  but i want to use my gpu which does around 300 to 400mhashs 5870  Is that to slow too for bitcoin mining? i can add my 5850 in crossfire with it but yea if its not going to bring any money in than i just give up on mining bitcoins.   


I read up on litecoins and i setup that so far and got that mining, Will litecoins bring any profit?
