I wanted to know if this is a upgrade worth the money. I use eyefinity on 3x 24 inch monitors and I play bf3 very often. However, I don't get very good performance. My CPU is the i7 870 2.93GHz. I will overclock it to 3.4GHz very soon. Is it worth the money to upgrade from my Sapphire 6870 to a Sapphire 7950 OC edition? Thank you
