Nice settings and a slew of games. It's nice to know which games are scaling well with my 4870 1GB cards in 2x Crossfire.

some crazily different results between games there. seems the nvidia cards are scaling a little more consistently, though.

Whoa, I wonder what part of Mass Effect they used for their benchmarks. Their results have the single 4890 averaging 24FPS and dipping to 16 at 1680x1050. I'm pretty sure I was getting much higher framerates at those settings on my puny 4850.

Thanks for posting OP. A good 3-way review includes analysis of how effective a third card is over a two card system, which the review included. Bang for the buck kinda goes out the window on the third card but it does help on average.

I admit my third 285 yields little return on investment (if we can even call it that); but it helps smooth out overall gameplay in most situations. Benchies are a snapshot. But smooth gameplay through various scenes is the real world application. It's playing those games maxed and them remaining smooth through tough scenes where I appreciate the extra horsepower.

Kudos to 4890.. it kicks good ass and offers excellent bang for the buck when buying two or three cards. I'd gladly have spent $199 times three over what I spent..

I'll add one more benchmark.

Dawn of War 2 - 29 min, 48 avg, and 92 max FPS with adaptive AA, 4x AA, and 16x AF at 1680x1050. Their setup is pretty much verbatim what I have setup for the 4870 2x.

i'll add 15 more benchmarks at the weekend; and i am also showing FrankenFire CrossFire-X scaling they don't; but i am not bothering with SLi this time

4870-X2 + 4870
4870-X2 + 4890
4890 + 4870
4890 + 4890

i have completed testing 11 Crossfire configurations with different clock speeds of the video card pairs, compared. Our conclusions are similar

Thanks for the link OP.

As soon as i get my 4890s benched tonight, I'll post some results compared to a 4870x2.

it eats X2 alive

and if you OC them to 975/1050 you will not care so much for X2 anymore
-Heck a pair of Overclocked 4890s are sometimes faster than TriFire

Sweet. That's what I was hoping for. I only benched 4 games before I sold my X2 but it should be interesting nonetheless.

I just got another 4870 512 for $120 to run in crossfire. I feel bad for my power supply, but I'll feel better running anti-aliasing at 1920x1200.
