Right now i'm rocking the Sapphire 6870 1gb and i was wondering if i should get the flew 6870 for cross fire cus it comes with a crossfire cable. my motherboard is an asrock extreme 3 gen3. Or should i just get one of the 7870s when they come out later this month. i'm debating this right now just because of the cost of the 7870's from what i'm seeing they could be a bit out of my budget. Just wondering if the upgrade would be worth it.
