I love this review ( but would have likes multi gpu setup test)
With sandibridge around the corner, the entrylevel gpus will be dimineshed, AMD is stepping up its game in the mid level gpu section. ( because it will soon be entry level and not midlelvel)
I don't like that ATI and NVIDIA cards are so far apart as to how they do Phys-X and other newer game technologies. I'd like to see them both cleave to standards so we could rate them in a better and fair way against one another. ATI says that Phys-X is closed by the other guy, and NVIDIA say's it isn't,..........what a crock. They should both do it all.
Not knowing if Phys-X and Cuda will take off and be a part of every game makes me lean towards buying the cards that have it built-in to them just to ensure that I don't have to buy all over again later just to be able to play the next new wazoo games that developers are dreaming up. Thanks for the considered look at these new AMD Cards.
thats what i get, cause with the new prices 460 worth more and better tesselations VS non
otherwise ati boys stay with the 5850
So the 5830 doesn't exist anymore !
ROFLMAO - It's a hoot seeing so many geeks claiming to know something, and the entire red rooster set of intertards cannot bring themselves to type 5 8 3 0 .
Wow.
What card has 1120 shaders ? LOL
There are no less than 8 different 5830's available on the egg right now, exceeding a few other " quantity models".
Out of the 20-30+ reviews, I've seen ONE that logically and honestly claimed one of the cards "being replaced" was the 5830.
We have 5870, 5850, 5830 - not like it's easy to miss the 3rd card. You really have to work at it.
Those the masses and the two competing companies rely on for releases, affect the market quite substantially, yet they miss the single 1120 shader card ATI had on the table, when the 2nd 1120 shader hits ? Widely IT'S NOT EVEN MENTIONED NOR CHARTED IN ENTIRE ARTICLES.
"It's low in production" is a joke.
I have no idea if it's pressure or brainwashing or incompetence, but in any case no excuse will satisfy, period. I'm certain you understand that.
Now that AMD has released another set of competitors to the 460 in very short order, the 5830 falls into the amnesiac category. 8 different 5830's are currently available on one of the very popular online purchasing sites.
I've seen just one review actually mention the 5830 when reviewing the Barts 6000 release.
Those of us who are awake, obviously in the minority, have reason to be disturbed.
26 cards in total.
No 5830.
I'm not here to criticize you, but your last response is quite surprising to say the least. I don't suppose any card other than the GTX460 1gig "has anything to do with a $250 6870" , or perhaps we could just have a review with the 6870 compared to the 5850 or just the 5870, whichever the 6870 happens to be closest to. I suppose by your statement that's the 5850.
I will find more than the 5850 in the bench charts won't I.
I am sorry logic and comprehension and honesty isn't in the mix, all too often.
Believe me, it's not a conspiracy. I don't think it could be even if we really, really tried.
While you're at it, go back and re-read the 6850 review. It was re-written to compare against the 5770 and 5830.
i wanna play crysis2 on max settings so... which graphic card sholud i bu.
plzzz help me :(
ma budget is around 350-400$
