4890 xfire vs 5970

[Jacky60]

I'm upgrading from 4890's at 900/1025 to 5970 and wondering if I'll see significant gains. Playing Arma 2, Crysis and Fallout 3 etc but Arma 2 is beating up my system.
If not would tri-fire with o/c 5970 and 5870 be best solution?

Quadfire is the most silicon horsepower you can practically stuff into a system today (2x5970). Tri-fire would be the second choice. If that much computing firepower won't do it for you at 1920x1200, nothing will.

At least for now.

Err I think the OP is upgrading to ONE 5970, not two...

You will see some performance gains, as a 5970 is about on par with 2x 5850 CrossFire, and obviously 5850 > 4890. Though at your resolution, I think even the 2x 4890s are perfectly fine.

Already committed to 5970 but with 4890 crossfire in Arma 2 get real slow downs (10-15 fps) and at 1920/1200 with 'normal aa and very high everything (xcept post processing normal) hovers between 20 and 40 fps mostly and just not quite there-i.e. drops to 20-27/29 too often. Also annoying microstutter -I'd call it pis poor fluctuating frame rate myself but whatever. Think we need a generation in GPU more before I'll get 60 fps all high and 4xAA

Go for it; you could grab a 5870 as well and tri-fire that setup for fun.
