XFire or Replacement

[WaQs]

Hi All,

I currently own an Asus EAHD5870 which until Battlefield 3 was working great, but I can't push run Battlefield 3 at 60fps on Ultra Settings. Can I achieve this by adding a second 5870 (Can I purchase any 5870 or does it have to be the same model/manufacturer), or should I look at replacing the gfx card.

My Motherboard is capable of running XFire or SLI.

Thanks in advance.

I'd really like to play the game on Ultra settings, I know it makes no difference at all to the gaming experience. With XFire 5870 can I expect to push 60fps at all times? I'm struggling to find benchmarks with XFire 5870s on-line.

Thank you all for your help, I'll purchase another card and go down the xfire route.
