Yo bro. How does your single 290 and Xfire 290 score in heaven 4 and Valley 1?. I ordered two of these 290's, arrived Thursday but one of them turned out to be faulty (defective Hynix RAM). The other one is working fine but seems to be scoring a bit on the low side in benchmarks compared to my previous 780GTX.
Waiting for replacement to arrive, but how do I use Xfire?. Never used AMD Xfire b4.
BTW, my 2x770GTX (maxxed out settings) has no problems playing BF4. Works flawlessly.
