XFX DD 7770 & BF3

[badoosh]

I have just bought my new PSU and my new GPU and was wondering if I can run it and still get good FPS in BF3.

System Specs:
Core i7 975x @ 4.2Ghz
12GB DDR3 Crucial 1600Mhz Ram
Silverstone Stryder 850w 80+ Gold PSU
ASUS Rampage III Formula Mobo
NZXT Switch 810 case (defective though)
Two Corsair Force GT 60GB SSD's Raid 0

One XFX DD 7770 1GB GPU

If I were to get a second 7770 would the performance match or even be better than my fried 6950 2GB?

Two in CF would be close to the HD6950

The HD 7770 crossfire setup will blow the hd 6950 & 6970 out of the water and sometimes even the 7950 in some benchmarks.( Except for the Skyrim benchmark where the results are terrible for the 7770s
