6870x2 and 6870 cf

right now i have 6870 CF but my gf needs a new graffics card so i was thinking about giving her 1 of my 6870's and buying a 6870x2 to run in tri fire. I only want to do this if it will run bf3 in eyefinity with at least high setting (would prefer ultra setting) at around 60 fps. My system is a 8150 oc to 4.6 ghz on a h100 on a asus crosshair V formula mobo 16 gigs 1800 mhz mem OC to 2050 mhz 850 Watt psu
So what do u guys think?
