Hi, just a quick question, is there any point crossfiring two Ati Radeon 1GB HD 5670 cards?
My mobo supports crossfire, and I'm looking to run three monitors. I already have two running from just one card.
I only run Microsoft Flight Sim X, currently on only one display (I would like it on three).
I can get around 10fps on the ground at busy airports and easily 20+ when in flight [1440x900].
Would crossfire improve my frame rate or am I limited by other components? What is the best way to check what is the limiting factor?
OS: Windows 7 Home Premium 32-bit.
CPU i3 540 3.06GHz
GPU Asus Ati Radeon HD5670 1GB
HDD: WD Caviar Black 640GB
RAM: Corsair XMS3 TWINX 4GB DDR3 1333MHz
MOBO: GIGABYTE GA-H55M-D2H
Sure you can run two 5670s in CF, but don't expect any miracles. If your second card has Display Port you could run all three monitors from a single card, but even with two of them you won't get great frame rates. Sure you'll have more GPU power with two, but the extra work added by a third monitor would basically leave your frame rates the same.
You're better off getting a more powerful card. If you want to run 3 monitors and have better FPS I say get at least a 6850. If you're fine with just two monitors then an Radeon 5770 or a GTX 460 768 would be the way to go.
