How to expand bf3 on second monitor

You can only do it with 2 cards and 3 monitors in SLI or crossfire as far as I know. I have 2 monitors as well but 2 different resolutions and 1 card myself and it wont work, tried it. At least not on a single Nvidia card it won't. Google or Youtube it.

SLI and crossfire are NOT required and its perfectly fine with 2 monitors. The resolutions should ideally be the same though. You gave zero information though, it will cut your FPS in half so you need a high end card, and you ABSOLUTELY DO NOT want to do this with BF3. Think logically. You will have a Bezel right in the middle of your screen. How are you going to see to aim or shoot?

Your cards do not support eyefinity and you cannot game on multiple displays. Only 5000 series and higher allow this. Your cards are also not powerful enough to drive multiple displays for gaming, I am surprised they even handle 1080p and as I already said it would be impossible to aim or see where you were going or shooting with only 2 displays in a FPS

ok thank you what card do you recomend 6570 be ok his hd

What settings? What FPS? If you want to game with good FPS and high settings on multiple 1080p displays you need something like a 7970. With the rest of the system being high end top. The 6570 isn't even really meant for gaming.

The lowest Toms recommends is the 6670, and they don't recommend it for 1080p. It would get about the sane FPS you get now with ONE monitor.

Yes technically a 6570 can do eyefinity, and in some very low end games like racing/flight Sims it would probably work. But multimonitor for high end triple AAA gaming is EXPENSIVE. A 6570 is probably going to have lower FPS than your current cards on a SINGLE monitor. Add a second monitor and it will get cut in half.

with a 6670 you MIGHT get 20 FPS average on low, doing down to 10. It will be unplayable and again you wont be able to even play the game because of the Bezel. What you want to do with your apparent system/budget does not make any sense and I would not at all suggest it.
