Excellent article! Thanks for all the relevant and pertinent information displayed very well.

I'm just a bit curious as to why you have used 2 Crossfire bridges. Page 4 of your article.
I understood that one was sufficient. I use only one and it works fine.
Bilko out.

Nice review, but I have one ENORMOUS complaint, and it's not just this site...

We've heard all this hype and fluff about DX11, and all the faboi screeching for ati and dx11 and the big fat beating it places on nvidia - even when ati couldn't deliver cards for their paper launch - but now we have 5770 and 5750 - and by GOD - in the one game BATTLEFORGE that has a dx11 feature - SSAO - the benches are done WITH IT OFF 100% OF THE TIME !
---
So, ALL the review sites I see do the same damned thing. The new DX11 cards 5750 and 5770 are benched in a DX11 game with all available DX11 features TURNED OFF !
---
Now, ati must have an enormously powerful hammer over the tops of the heads of the reviewers- not a single one with the integrity or GUTS to post the truth about these cards and their PATHETIC dx11 performance.
---
So what we have is a load of crazed red fanbois running around the net screaming 5770 and 5750 and dx11 - and THEY FAIL SO BADLY with dx11 ON, that the benches are NOWHERE.
Thanks for the GIGANTIC LIE AND COVERUP !

Way to go totally DISHONEST ati.

i agree with Silicondoc, Test those cards also in Dx11.
Overall i really enjoyed the review thanks for your time and effort.

The 5750 and 5770 are quite disappointment from ATI. The price/performance is realy weak.
I mean tell me one reason why someone owning a hd4850 (like me) should upgrade to 5750 ? For more money i get same performance and dx11 which if i turn on i loose 30% performance. 5700 cards are 40nm and use simple 128bit board dont see where is the problem.

The logic would be to upgrade from 4850 to 5850 but thats a 300+ dolar card. I did expect the 5700 series to be the new low end and cost much less, not same as the old 4800 series and with higher price.

But thats happen when there isnt competition. I wont buy anything untill the prices are real or my card is broken.

Every one can make a game that will choke even the fastest cards , but who would buy it. I dont see the logic of making a next generation card (4000 vs 5000) when it doesnt increase the performance for the same amount of money. Then it happens that a old downgraded nvidia 7800 card in PS3 can make pc graphic look embarassing (like the FF XIII on PS3).

yeah see if your going from last years top end to this yrs mid/low end then you should be ready for disappointment.... me on the other hand went from 2x cf'd ATI HD2600XT DDR4 cards to a single HD5770 DDR5 card and wow what a difference it makes from a max of 40fps in Unreal 3 to over a 100fps avg just makes for me a better playable game and now one i want to play again i really couldn't give a toss about dx11 and when i do i'll buy another 5770 and run them CF modeand if thats not enough maybe just maybe I'll split for an 5870!!
