I currently have one 6870 that i have decently overclocked. I recently started playing BF3 and this card is definately not up to the task. I am wondering since it would only cost me another ~$175 if another in crossfire mode would be a substantial increase or not.

Also, I have a 700w psu and an i7-920 that is overclocked to 4ghz. Will this be enough psu?
