5870 Crossifre?

[eloplayspolo]

Currently I am running a Single 5870 Vapor-X.
I am using Dual 25" 1080P LCDs and I plan to add a 3rd for Eyefinity.
Processor i7 930 @ 4.01
6GB of 1600MHZ DDR3
Gigabyte UD3R allowing me to run Dual 16X PCI-Expresss cards
120GB OCZ Agility 3

I am thinking of purchasing either another 5870 and the additional LCD.
Ebay is showing these going from anywhere between 120 and 200.

I have the Vapor-x Edition card as well as the box and all parts, so i assume i could get 200 for it if i chose to sell it.


Questions: how well will 2 5870s run BF3 in Crossifre?

Should i sell the 5870 and get another card?

Thank you in advance.

I have a 5870 and thought about CFing it, decided to just wait for the 7000 series cards, scalling is pretty bad in the 5000 series
