    If you pick up three Radeon HD 5770 1024MB cards say at 150 USD would that bring game performance into the uber high-end level Well we wanted to find that out. So we took a new eVGA P55 Classified...

    Epic scaling.

    Epic scaling is an understatement if you look at it, and think on it. Personally, when I saw the first results for the 5770 I was a bit disappointed with it. It seemed to be an exact equal to a 4870 (sometimes better sometimes worse).

    However, if you look at the results here, you'll see that the 5770 crossfire almost always beats the 4870x2. Kind of blows my mind.

    O my... there really is absolutely no proper reason to get trifire with HD 5770s. If you got that much money, just grab a HD 5850/5870 CF and enjoy much less problems.

    Well you wouldn't be able to get 5850 or 5870 crossfire for the same price. Cheapest I've found a 5850 is 289 and cheapest I've found a 5870 is 379. So, if you do the math, you could have 3 way 5770 for about 100 dollars less than two way 5850.

    But I agree there's no reason for it. The CPUs seem to trip all over themselves when subjected to that kind of overhead.

    in some of the games the results supprised me , in other games the 3 way crossfire seems to work worse than 2 . seems odd but thats life lol

    5770 Trifire- $479.97
    5850 Crossfire- $559.98
    5870 Crossfire- $779.98
    Any problems you would have with these in trifire, you would most likely have in crossfire of the 5850 and or 5870. Since they're all on the same system. Plus, you're still saving money.

    The game you notice this the most is Call of Duty. It's not a problem with the 3 video cards scaling, but it's a bottleneck from the cpu.

    what i want to know is , why do they keep making graphic cards this fast when the rest is not catching up ? . no wonder you get bottlenecking

    Because then we couldn't run 3d apps better. Plus, think about future games and applications too. It's not up to the maker of the video card to make sure the cpu can keep up with the rest of the system, it's the cpu maker.

    Have you even had a tri-fire setup? I have and the 3rd card doubles the possible problems over CF. They are definately very different system.

    O yeah save couple bucks for lots of possible issues. Sounds good. Even 2 card setups are sometimes skethy.

    Scaling compared to older series of cards has increased a lot more. Even more when the drivers given with the 5xxx series have improved a lot. No multiple GPU setup is going to be perfect. Hell, no single gpu setup is going to be perfect.

    And if you call $100-$200 a couple of bucks, then I'd like to know what you do for a living, because I want in. :D

    I am not talking about scaling alone. Go ahead and get a HD 5770 trifire, but never ever come here complain about it then.

    3x HD 5770 = 480 bucks. 2x HD 5850 540 bucks. Prices takem from GURU3D HD 5770 article.

    edit: I am going with Hilbert in this one:

    That's a very informative article.

    I'll definitely stick to two 5850 cards. It looks too much of a hassle to have 3 or more. Besides my CPU couldn't cope with them.

    That's fine. And I won't, since I don't ever plan on getting 3 5770s considering the fact I only have 2 PCIE slots and not 3.

    Aside from drivers which are sure to mature, the biggest issue with trifire is the cpu bottlenecks it.

    Good review, but I would like to see Hilbert review quad-SLI (dual GTX 295), 3xSLI GTX 285, and 3xSLI GTX 275 setups so we can directly compare the benchmarks to the ones gleaned from this 5770 3-way CrossfireX review. The last 3-way GTX 285 SLI review he did used different games and different graphs than the ones he used here.

    You listening Hilbert?

    Thanks for the review, not to nitpick, but I think the color key on the RE 5 benchmark needs a slightly larger font I could hardly read it on my laptops screen. (17" 1440x900)

    It does, I can't see it on mine either.
