I have got a question. I had bought new pc and i did a mistake with motherboard... I bought Asus M5A97 R2.0 AMD 970 and it has 2 pcie - one x16 and one x4... If i would do a crossfire in the futube, it could be bad? If i had x16/x8 it should be a more better? Because i wanted to do a crossfire after one/two years but if it would be very limited it is nonense.

And could I do crossfire with 270x/7850?
