Hello, I'm a super noob to this so bare with me. This my first build so I'm not going to tackle Oc'ing right out the blocks. I just ordered a Gigabyte intel z77 lga1155 im just trying to figure out if the ASUS HD7870-DC2-2GD5 would be a good match up? I also ordered a i5-3570 processor. I was thinking of getting two HD7870's but 1 the wife would have my head and 2 I think I would run into a bottle neck issue with the mobo if I'm not mistaken. Any help would be awesome thanks.
