Upgrade: Max card to crossfire with a 270x

[Stevoisboss]

I am planning on upgrading my rig this summer when the new amd cards come out and prices drop. I was wondering what is the best card I could crossfire with my 270x and if it would be worth it. Pc:http://

Well based on your budget:
GTX1070 if you have $400 to spend
GTX980 or GTX970 depending on what kind of deals will come available. Probably 330-350 / 220-260 but i'm just guessing here.
Generally i wouldn't crossfire that card, just get a newer faster single card and the above would fit the bill.
