4890 vs 5770...how important is DX11 support?

Cause it(5770) have dx11 on it, which is 4890 not...
So if you aren't going for multiple monitors then 4890 is a better choice for about 1-2 years...
Anyone?

There is I believe 1 direct x11 game out now. (Dirt maybe, can't recall) More will be coming but it is hard to say how rapidly it will be adopted by game developers. For now direct x 10.1 will be the standard for win 7 for a while. Currently if I was in the market I would look at the 4890, but then I chnage my card about every two years.

DirectX is a software of Microsoft and the games than we play use that to run.
the 5770 has support this directx 11 for run new games, actually dont have need it. And of course, the diference is because with new directx, games will be more perfome (frame per second) and too better graphics  

Conclusion: certainly is being developed game than use directx 11, so if you want play this games buy 5770, and too diference between 4890 and 5770 it is not so higher  

sorry for bad english

It will likely be quite a while(several years) before significant games will actually require DX11 so if you are worried about not being able to play certain games that shouldn't really be an issue. However a lot of games in the near future will use DX11 to make games look better and with an HD4890 you wont be able to use those settings. There are a few out already, most notably Dirt 2 and the new Stalker game.
The other advantage of the HD5770 is the low heat/power efficiency which is good in general but especially so if you want to crossfire in the future.

thats right =]

So if u wouldn't on a plan to upgrade your card for 1-2 years then i suggest to take 4890...
But now it's on your hands now...  

The question how important is DX11 to you?

I slapped a HD 5850 in my Win XP machine 'cause I want performance. I'll upgrade to Win 7 soon enough, but not because of DX 11.

I would say it depends what you are doing. New build or upgrading ? As already said what timeframe do you think you will update again in ?
If your looking at a new build then i would get a 5770, if upgrading then it depends what from and what OS you have.
If the OS is DX11 capable then it a bit pointless not getting a DX11 GPU for my money.
My personal situation is that i have all the parts sitting here, new HDD copy of W7 etc and i am just waiting for the DX11 cards prices to come down. Dont really care if they dont as im in no need of a performance upgrade just yet, and as people have said DX11 games have yet to hit us in any numbers.

The 5770 supports DirectX11, which is the latest version (so more longevity comes along). Besides being newer, DX11 also enables smoother curves and shapes in 3D models (a rocky desert in a video game world for example) through tessalation and a whole bag of other goodies.
Basically, in today's games a 4890 will achieve higher FPS and similar graphics quality. In tommorow's games, a 5770 will achieve enormously better graphic quality, perhaps at slightly lower FPS (altough both yield an FPS so high the difference can't be seen by the human eye).
On top of that, the 5770 is smaller and thus easier to install, consumes less power (a LOT less) and is far more silent.
Note it's also very easy to crossfire two 5770's once a single doesn't yield the performance you desire anymore (so years from now). By then they'll be dirt cheap, and the low power consumption and heat makes it perfectly possible. Crossfiring a 4890 will be a lot harder. The sheer amount of heat you'd have to get rid off alone makes it a feat nigh impossible without expensive watercooling and a monstrous case.

DX11 is importat because others games in the future will require it to run.

and if i want performance without dx11, i will buy 4890
its cheaper than 5850 and has more performance

What??? DX11 is not that important at all, unless there is a specific DX11 title that you are waiting on. I have been using XP (DX9) since it came out and it plays any game just fine. Maybe in a year or two from now DX11 will be needed since there will be alot more games that will benefit from it... So don't go buy a GPU just cause of the DX feature, buy a card that will run your favorite game at your desired settings.

The 5850 will eat a 4890 for lunch

i want say
if he want performance buy the 4890, it dont have support to dx11 but its (4890) cheaper than 5850

sorry for bad english hahahha

Theres several DX11 games coming within a couple months, the 5850 beats the 285 as well as a 4890

The 5850 has stellar performance, the new smaller gpu die that produces less heat uses less power.
The 5850 also costs ALOT more thand the 5770.
The 5770 shares those traits but does not have stellar performance , it has good performance.
The 4890 beats the 5770 easily. So you have to weigh the other factors, price, heat, dx11 (not important IMO).

wow
i didnt see it, 5850 eat easy =]

Id guess that in mid to lower cards DX11 first gen , DX11 wont be as important, as the perf may not be there for the improved gfx.
While DX11 causes more of a hit, it also gives more visuals, but all this is going to vary from game to game, thus affecting different cards differently.
Without those other games out, ones you may wish to play in DX11, theres simply no way to tell at this point, but DX11 is forwards looking, tho again, the 4890 is slightly more powerful too

DirectX 11 games are being made and will be released through the year. If these titles are actually going to be what you want to play, well we won't know that until the games come out. The thing here is do you take the 4890 and get the card that plays the games you want right now at the best FPS, and risk in a few months a game that you end up really wanting to play that is DirectX11 but not have a card to support it. But there might not be any games that come out for another year or two that are DirectX 11 that you specificaly want to play.

Its really a look at what do you plan on playing in the future. Personaly i just built a new system and wanted to make sure that i didn't need any big upgrades for at least a year or two for that PC, so i went with a 5770. I must say that i love how well Dirt 2 runs on it (came free with the card i bought). This was the first DirectX11 game to be released and if the graphics in here are an indication of where this card can go, i believe it has a ver nice future.

Just my 10 bits.

i shall be getting the 5770 for dx11 and future games it will replace my ati 1950 pro, and will have about 1/3 increase in bandwidth compared to the 1950 pro, then i will crossfire it later when i upgrade my main system. in the mean while my current graphics card is starting to struggle with the latest games, £130 for a noticeable increase in performance is good value to me, the 5770 has 128 bit memory interface, where the 5870 has 256 bit memory interface, but is out of my budget. my system is based on asrock duel sata 2 m/b a 4200 cpu o/c to 2800 gig 2gig ram win 7 64bit. its getting long in the tooth, but i can play top games (just) but i have to loose most of the eye candy, two graphics cards in crossfire on the right m/b that is 16/16 pcie 2.0 is better than a 8/8 or 16/8 crossfire setup on some m/b so don't skimp on the m/b its the heart of the system the rest can be upgraded later.
